Overview

This section describes how to install and configure the Dell small computer system interface (SCSI) device drivers included with your Dell PowerEdge 6300 computer system. These device drivers are designed to work with the dual Adaptec AIC-7890 low voltage differential (LVD) Ultra2 / Wide SCSI-3 controllers and the Adaptec
AIC-7860 Ultra/Narrow SCSI-3 controller on the system board.

The AIC-7890 controllers support up to six internal SCSI hard-disk drives via a standard SCSI backplane board while the AIC-7860 supports up to three externally accessible SCSI devices in the system's external drive bays, such as the CD-ROM and a tape drive unit.

The Dell PowerEdge 6300 system can support up to two 1-inch SCSI drives in the external drive bay with the optional removable drive cage.

The AIC-7890, AIC-7860, and the optional AHA-2940U2W SCSI controller card are all part of the Adaptec 78xx series of SCSI controllers, and all use the 78xx series of SCSI device drivers provided by Dell. The Adaptec SCSI basic input/output system (BIOS), which is stored in your computer system's flash memory or on the optional
AHA-2940U2W SCSI controller card, links these SCSI device drivers to the AIC-7890 and AIC-7860 SCSI controller chips or the optional AHA-2940U2W SCSI controller card.

If you are using an optional Dell PowerEdge Expandable RAID Controller, refer to either of the following sections, Installing SCSI Drivers for a Dell PowerEdge Expandable RAID Controller in Windows NT 4.0 or Installing SCSI Drivers for a Dell PowerEdge Expandable RAID Controller in Novell NetWare 4.11. You can also refer to your Dell PowerEdge Expandable RAID Controller documentation for information on installing your SCSI device drivers.

For instructions on installing SCSI hardware devices such as hard-disk drives, tape drives, or CD-ROM drives, trained service technicians should see Chapter 9, "Installing Drives in the External Bays," and Chapter 10, "Installing Hard-Disk Drives," in your Installation and Troubleshooting Guide. After the SCSI devices are installed, you need to install and configure one or more SCSI device drivers so that your SCSI devices can communicate with your operating system.

SCSI device drivers are provided for the following operating systems:

  • Microsoft Windows NT Server 4.0
  • Novell NetWare 4.11

See Using the Dell Server Assistant CD, for instructions on creating a diskette of drivers for your operating system. For instructions on configuring the SCSI device drivers, see the appropriate subsections in this section.

2. Install the EZ-SCSI software using the instructions provided with your system, and install the CD-ROM driver using the instructions provided with the drive.

3. Insert the Novell NetWare 4.11 CD or the Dell IntranetWare Support CD into the CD-ROM drive and change to the CD-ROM drive letter.

4. Run install.bat from the CD.

NetWare 4.11 detects the Dell PowerEdge Expandable RAID Controller (identified as "MegaRAID" in the system message).

5. Insert the RAID driver diskette created for NetWare 4.11 that you created from the Dell Server Assistant CD and press <Enter>.

NOTE: Do not use the drivers provided on the NetWare CD.

6. Follow the instructions on the screen to install the RAID drivers and to complete the NetWare installation.


The readme.txt File

The readme.txt files that are included with your SCSI device drivers (in the device driver \pe6300\scsi subdirectory on the CD) provide updates to the information in this section

Use the editor included with your operating system to view or print the readme.txt file or any other readme file.


The SCSISelect Utility

The BIOS for the built-in dual Adaptec AIC-7890 and AIC-7860 SCSI controllers includes the menu-driven SCSISelect configuration utility, which allows you to change SCSI controller settings without opening the computer. SCSISelect also contains SCSI disk utilities that let you low-level format or verify the disk media of your SCSI hard-disk drives.

SCSISelect Defaults

The defaults for the optional Adaptec AHA-2940U2W SCSI controller and the built-in AIC-7890 and AIC-7860 SCSI controllers are shown in Table 1. These default s are appropriate for most Peripheral Component Interconnect (PCI) systems. Run SCSISelect only if you need to change any of the default s .

NOTES: The SCSISelect Utility must be run for both the AIC-7890 SCSI controllers and the AIC-7860 SCSI controller if you need to change the configuration settings.

The term host adapter is used throughout this chapter to refer to the built-in AIC-7890 and AIC-7860 SCSI controllers or the optional AHA-2940U2W SCSI controller card.

To change the settings, see the descriptions of each setting in the following subsections. To change any of the default s or to format or verify a disk, see Starting the SCSI Select Utility.

SCSI Bus Interface Definitions

The basic host adapter settings are the SCSISelect settings most likely to require modification:

  • Host Adapter SCSI ID -- This option sets the host adapter's SCSI ID. The default setting is SCSI ID 7, which allows the host adapter to support narrow SCSI devices in addition to wide SCSI devices. Dell recommends that you leave the host adapter set to SCSI ID 7.
  • SCSI Parity Checking -- This option determines whether the host adapter verifies the accuracy of data transfer on the SCSI bus. The default is Enabled. You should disable SCSI Parity Checking if any SCSI device connected to the host adapter does not support SCSI parity; otherwise, leave it enabled. Most SCSI devices support SCSI parity. If you are unsure if a device supports SCSI parity, consult the documentation for the device.
  • Host Adapter SCSI Termination -- This option sets termination on the host adapter. The default for the Adaptec AIC-7860 host adapters is Enabled; the default for the AIC-7890 host adapter is Automatic. Dell recommends that you leave this option set to the default.

Boot Device Options

The boot device options allow you to specify the device from which to boot your system :

  • Boot Target ID -- This option specifies the SCSI ID of the device from which you boot your system. SCSI IDs are set for the hard-disk drive according to the drive's location on the backplane board for the SCSI ID of each drive location. The default for Boot Target ID is SCSI ID 0.
  • Boot LUN Number -- If your boot device has multiple logical unit numbers (LUNs) and Multiple LUN Support is enabled (see "Advanced Host Adapter Settings" found later in this section), this option allows you to specify a particular LUN from which to boot on your boot device. The default is LUN 0.

SCSI Device/Configuration Settings

The SCSI device/configuration settings allow you to configure certain parameters for each device on the SCSI bus. To configure a specific device, you must know the SCSI ID assigned to that device. If you are not sure of the SCSI ID, see Using the SCSI Disk Utilities.

  • Initiate Sync Negotiation -- This option determines whether the host adapter initiates synchronous data transfer negotiation (sync negotiation) between itself and the device. The default is Yes.

Synchronous data transfer negotiation is a SCSI feature that allows the host adapter and its attached SCSI devices to transfer data in synchronous mode. Synchronous data transfer is faster than asynchronous data transfer.

The host adapter always responds to sync negotiation if the SCSI device initiates it. If neither the host adapter nor the SCSI device initiates sync negotiation, data is transferred asynchronously.

Normally, you should leave the Initiate Sync Negotiation enabled, because most SCSI devices support synchronous negotiation and because it allows for faster data transfer.

NOTE: Some older SCSI-1 devices do not support sync negotiation. This may cause your computer to operate erratically or hang if Initiate Sync Negotiation is set to Yes. Set Initiate Sync Negotiation to No for these devices.
  • Maximum Sync Transfer Rate -- This option sets the maximum synchronous data transfer rate that the host adapter supports. The host adapter supports rates up to 80 megabytes per second (MB/sec). The default is 80 MB/sec (the maximum).

If the host adapter is set to not negotiate for synchronous data transfer, the maximum synchronous transfer rate is the maximum rate that the host adapter accepts from the device during negotiation. (This is standard SCSI protocol.)

  • Enable Disconnection -- This option (sometimes called disconnect/reconnect) determines whether the host adapter allows the SCSI device to disconnect from the SCSI bus. Enabling disconnection allows the host adapter to perform other operations on the SCSI bus while the SCSI device is temporarily disconnected. The default is Yes.

Leave Enable Disconnection set to Yes if two or more SCSI devices are connected to the host adapter. This optimizes SCSI bus performance. If only one SCSI device is connected to the host adapter, set Enable Disconnection to No to achieve slightly better performance.

  • Initiate Wide Negotiation -- This option determines whether the host adapter attempts 16-bit data transfer instead of 8-bit data transfer. The default is Yes.
NOTE: Some 8-bit SCSI devices may have trouble handling wide negotiation, which may result in erratic behavior or a hang condition. For these devices, set Initiate Wide Negotiation to No.

When this option is set to Yes, the host adapter attempts 16-bit transfer. When this option is set to No, 8-bit data transfer is used unless the SCSI device itself requests wide negotiation. The effective transfer rate is doubled when 16-bit data transfer is used because the data path for wide SCSI is twice the size of normal 8-bit SCSI.

  • Send Start Unit -- This option determines whether the send start unit command is sent to the SCSI device during the boot routine. The default is Yes.

Setting this option to Yes reduces the load on your computer's power supply by allowing the host adapter to start SCSI devices one at a time when you boot your system . When this option is set to No, the devices are allowed to start at the same time. Most devices require you to set a jumper before they can respond to this command.

NOTE: For many devices, if Send Start Unit is set to Yes, the boot routine time will vary depending on how long it takes each drive to start.
  • BIOS Multiple LUN Support -- This option provides support for peripherals that contain multiple SCSI devices, such as RAID subsystems and CD-ROM changers.
  • Include in BIOS Scan -- This option enables you to set whether the system BIOS scans this device during system start-up . The default is Yes.

Advanced Host Adapter Settings

The advanced host adapter settings should not be changed unless absolutely necessary. These values are set by Dell, and changing them may cause conflicts with the SCSI devices.

  • Host Adapter BIOS -- This option enables or disables the host adapter BIOS. The default is Enabled.
NOTE: Several SCSISelect options are not valid unless the host adapter BIOS is enabled.

If you are booting from a SCSI hard-disk drive connected to the host adapter, the BIOS must be enabled. You should disable the host adapter BIOS if the peripherals on the SCSI bus (for example, CD-ROM drives) are all controlled by device drivers and do not need the BIOS.

  • Support Removable Disks Under BIOS As Fixed Disks -- This option controls which removable-media drives are supported by the host adapter BIOS. The default is Boot Only. The following choices are available.
CAUTION: If a removable-media SCSI device is controlled by the host adapter BIOS, do not remove the media while the drive is on or you may lose data. If you want to be able to remove media while the drive is on, install your removable-media device driver and set this option to Disabled.
  • Boot Only. Only the removable-media drive designated as the boot device is treated as a hard-disk drive.
  • All Disks. All removable-media drives supported by the BIOS are treated as hard-disk drives.
  • Disabled. No removable-media drives are treated as hard-disk drives. In this situation, software drivers are needed because the drives are not controlled by the BIOS.
  • Plug and Play SCAM Support -- This option provides automatic configuration of SCSI devices in operating systems that support Plug and Play. Dell recommends that you leave this option set to Disabled.
  • Reset SCSI Bus at IC Initialization -- This option enables the SCSI bus to be reset when the controller is initialized. The default is Enabled.
  • Extended BIOS Translation For DOS Drives > 1 GB -- This option determines whether extended translation is available for SCSI hard-disk drives with capacities greater than 1 gigabyte (GB). The default is Enabled.

When you partition a hard-disk drive larger than 1 GB, use the MS-DOS fdisk utility as you normally would. Because the cylinder size increases to 8 MB under extended translation, the partition size you choose must be a multiple of 8 MB. If you request a size that is not a multiple of 8 MB, fdisk rounds up to the nearest whole multiple of 8 MB.

  • Display <Ctrl><a> Message During BIOS Initialization -- This option determines whether the Press <CTRL><A> for SCSISelect (TM) Utility. message appears on your screen during system start-up. The default is Enabled. If this setting is disabled, you can still run the SCSISelect utility by pressing <Ctrl><a> after the host adapter BIOS banner appears.
  • Multiple LUN Support -- This option determines whether your system supports booting from a SCSI device that has multiple LUNs. The default is Disabled. Enable this option if your boot device has multiple LUNs.
  • BIOS Support For Bootable CD-ROM -- This option determines whether the host adapter BIOS provides support for booting from a CD-ROM drive. The default is Enabled.
  • BIOS Support For Int 13 Extensions -- This option determines whether the host adapter BIOS supports disks with more than 1024 cylinders. The default is Enabled.
  • Support For Ultra2 SCSI Speed -- This option determines whether the host adapter supports the fast transfer rates (20-80 MB/sec) . The default is Enabled.

Starting the SCSISelect Utility

You can start the SCSISelect utility by pressing <Ctrl><a> when the following prompt appears briefly during start-up:

Press <CTRL><A> for SCSISelect (TM) Utility.

The first menu displays the Configure/View Host Adapter Settings and SCSI Disk Utilities options.

Using SCSI Select Menus

SCSISelect uses menus to list options you can select. To select an option, use the up- and down-arrow keys to move the cursor to the option; then press <Enter>.

In some cases, selecting an option displays another menu. You can return to the previous menu at any time by pressing <Esc>. To restore the original SCSISelect default values, press <F6>.

Using the SCSI Disk Utilities

To access the SCSI disk utilities, select the SCSI Disk Utilities option from the menu that appears when you start SCSISelect. When the option is selected, SCSISelect immediately scans the SCSI bus (to determine the devices installed) and displays a list of all SCSI IDs and the device assigned to each ID.

When you select a specific ID and device, a small menu appears, displaying the Format Disk and Verify Disk Media options.

  • Format Disk -- This option runs a utility that allows you to perform a low-level format on a hard-disk drive. Most SCSI hard-disk drives are formatted at the factory and do not need to be formatted again. The Adaptec Format Disk utility is compatible with the vast majority of SCSI hard-disk drives.
CAUTION: The Format Disk option destroys all data on the hard-disk drive.
  • Verify Disk Media -- This option runs a utility that allows you to scan the media of a hard-disk drive for defects. If the utility finds bad blocks on the media, it prompts you to reassign them; if you select Yes, those blocks are no longer used. You can press <Esc> at any time to exit the utility.

Exiting SCSI Select

To exit SCSISelect, press <Esc> until a message prompts you to exit. (If you changed any 78xx series host adapter settings, you are prompted to save the changes before you exit.) At the prompt, select Yes to exit, and then press any key to reboot the computer. Any changes you made in SCSISelect take effect after the computer boots. (You can select No at the prompt if you are not ready to exit SCSISelect.)


Installation for Windows NT 4.0

This section provides the following information about installing the Dell SCSI drivers for the Microsoft Windows NT 4.0 operating system:

  • Installing the SCSI drivers for Windows NT
  • Removing a host adapter
  • Swapping a host adapter
  • Restoring a configuration if Windows NT fails to boot

Installation Overview

This section provides the information needed to install and use the Dell SCSI drivers for the 78xx series of SCSI controllers with Windows NT.

NOTE: If Windows NT was factory installed by Dell, the AIC-78U2 and AIC-78xx drivers are preinstalled.

The Windows NT 4.0 driver diskette you create for the Microsoft Windows NT Server operating system contains the files needed for driver installation. The diskette contains the following files to be used with Windows NT:

  • aic78u2.sys -- Adaptec's driver for the 7890 SCSI controller for Windows NT
  • aic78xx.sys -- Adaptec's driver for the 7860 SCSI controller for Windows NT
  • oemsetup.inf -- A file used by Windows NT Setup for driver installation
  • readme.txt -- A text file describing the Adaptec 78xx driver for Windows NT

Using Windows NT 4.0 to Install the Driver

To install the SCSI drivers, use the following procedure:

1. Create the Windows NT 4.0 driver diskette from the Dell Server Assistant CD.

2. Restart Windows NT Setup.

Windows NT copies files to your system and automatically reboots your system.

At the first blue screen after reboot, Windows NT Setup will display the following message:

Setup is inspecting your computer's hardware configuration...

3. Press <F6>.

The following message appears:

Setup could not determine the type of one or more mass storage devices installed in your system, or you have chosen to manually specify an adapter.

4. Type s.

A list of supported SCSI host adapters appears.

5. Click Other.

6. Insert the Windows NT driver diskette you created into the diskette drive.

7. Click the Start button, then click Run and type a:\ in the Open dialog box.

8. Type s.

9. Select the host adapter from the list.

For the Adaptec AIC-7890 SCSI controller, select Adaptec AHA-294xU2/295xU2/AIC-789x PCI Ultra2 SCSI controller (Windows NT 4.0).

For the Adaptec-7860 SCSI controller, select Adaptec AHA-290x/291x/294x/394x/494x/AIC-78xx PCI SCSI Controller (Windows NT 4.0).

10. Press <Enter>.

The driver is copied from the diskette to your system.

11. Repeat steps 8 - 10 for each SCSI host adapter installed on the system.

12. Click Yes when prompted to restart the system, and remove the diskette from the diskette drive.

After the system reboots, the new drivers are active. Some drive letter assignments may have changed from the previous configuration.

Removing a Host Adapter

Removing a PCI expansion-card SCSI controller is as simple as physically removing it from its slot when your computer is shut down. Windows NT boots and functions properly in this configuration, but a warning message is generated every time you boot Windows NT.

CAUTION: If you have removed a host adapter but still have other host adapters of the same type installed in your computer, do not use Windows NT Setup to remove the device driver.

To eliminate the warning message, you must update the Windows NT software configuration as follows:

1. Select and start the Windows NT Setup program.

There is a brief pause while Windows NT Setup scans your hardware configuration.

2. Select the Options pull-down menu, and then select Add/Remove SCSI Adapters.

The SCSI Adapter setup program displays a list of all host adapters currently installed.

3. Select the host adapter you want to remove, and click Remove. When the Windows NT Setup program asks you for confirmation, click OK.

Because SCSI device drivers are loaded during system start-up and because they may be needed to load Windows NT itself, a message may appear warning you that Windows NT may not start if you remove the SCSI adapter.

4. When you are sure you are removing the correct host adapter type, click OK.

5. Return to step 3 if you want to remove driver support for other types of host adapters, or click Close to exit the SCSI adapters portion of Windows NT Setup.

6. Close the Windows NT Setup program. When the following message appears, click OK to exit:

The changes you have made will not take effect until the computer is restarted.

If this message does not appear, no changes have been made to the Win­dows NT system configuration.

7. Restart your computer.

NOTE: The Windows NT Setup program does not delete the device driver from your hard-disk drive; it only updates Windows NT software configuration information so that the device driver is no longer loaded during system start-up.

Swapping a Host Adapter

The procedure for swapping one type of host adapter for another is similar to the procedure for adding a host adapter, except that you make all software configuration changes while Windows NT is running--before you make the hardware changes.

1. Install the driver for the new host adapter by following the steps in "Installation for Windows NT" found earlier in this section.

It is not essential to remove the device driver for the host adapter you are replacing. Windows NT dynamically detects the absence or presence of host adapter hardware, and no problems should arise if you leave the existing device driver installed. You can remove the device driver later, after you have successfully rebooted Windows NT. However, if you leave the driver in, the system alerts you with an error message about the extra device driver every time you boot. See the previous subsection, "Removing a Host Adapter."

2. After the new device driver is installed, shut down Windows NT and replace the existing host adapter.

3. Restart your computer and Windows NT.

Some drive letter assignments may have changed from the previous configuration.

Troubleshooting for Windows NT

The boot manager for Windows NT contains recovery logic to allow you to return to the last known good configuration. If you have changed your host adapter configuration and Windows NT no longer boots, follow these steps to recover:

1. Undo any hardware changes you have made to the computer since it was last operational.

2. Reboot the computer.

Watch the display carefully during start-up. If the following message appears, press the spacebar key, press <l> at the next screen, and then follow the instructions on the screen to continue booting with the last known good configuration:

Press spacebar NOW to invoke the Last Known Good menu

3. When your computer is operational again, check all of the hardware and software configuration changes you want to make. Look specifically for conflicts with parts of the existing system configuration that are not being changed.

If you cannot determine the source of the error, contact Dell for assistance. See Chapter 11, "Getting Help," in the Installation and Troubleshooting Guide for instructions on contacting Dell for technical assistance.


Installation for Novell NetWare  4.11

This section provides the following information about installing the Dell SCSI drivers for NetWare 4.11:

  • Installing the EZ-SCSI utility
  • Installing the Novell NetWare 4.11 operating system
  • Installing and updating the Dell SCSI driver for NetWare 4.11
  • Automatic driver loading using startup.ncf and autoexec.ncf
  • Booting a NetWare server from a SCSI drive, formatting media, and using removable media
  • Troubleshooting error messages generated during initialization

Installation Overview

This subsection provides the information needed to install and use the Dell SCSI drivers for Novell NetWare 4.11. The Dell SCSI drivers for NetWare support the optional Adaptec AHA-2940U2W and all Adaptec 78xx series SCSI controllers.

Before you begin installation of the SCSI drivers for NetWare, you must create a diskette of drivers for NetWare 4.11 and a diskette that contains the Adaptec EZ-SCSI utility.  Using the Dell Server Assistant CD provides instructions for creating these diskettes.

The Dell SCSI drivers for NetWare are fully tested and approved for NetWare. The NetWare scsi subdirectory on the NetWare 4.11 drivers diskette you create contains files to be used with NetWare 4.11. The following files appear in the scsi subdirectory on the NetWare driver diskette:

  • readme.txt -- An American Standard Code for Information Interchange (ASCII) text file describing Adaptec's drivers for NetWare
  • aic78u2.ham -- NetWare driver for Adaptec's 7890 and AHA-2940U2W Ultra2 SCSI series host adapters
  • aha2940.ham -- NetWare driver for Adaptec's 7860 and AHA-2940UW SCSI host adapters
  • nwaspi.cdm -- Adaptec's device driver for a CD-ROM drive
  • nbi.nlm -- File required by the NetWare bus interface
  • nwpa.nlm -- File required by the NetWare bus interface
  • nwpaload.nlm -- File required by the NetWare bus interface
  • cdrom.nlm -- File required by the NetWare bus interface

In addition, the scsi subdirectory on your NetWare 4.11 drivers diskette contains the following files:

  • aic78u2.ddi -- A driver definition information file for the 78xx Ultra2 SCSI series host adapters that provides setup information to NetWare during installation; NetWare can then prompt you with parameters to be configured for the device driver during the installation process.
  • aha2940.ddi -- A driver definition information file for the AHA-2940U2W host adapter .
  • aspicd.ddi -- A device driver definition file.
  • aspitran.ddi -- A device driver definition file.

To begin driver installation, first load the EZ-SCSI utility as described in the following subsection, Installing EZ-SCSI. Then if you are performing a first-time NetWare installation, see Installing NetWare and the Driver found later in this section. If NetWare is already installed in your system, see Using NetWare to Install or Update the Driver.

NOTE: Your system must have a bootable version of MS-DOS installed before you can complete the Novell NetWare installation.

Installing EZ-SCSI

The Adaptec EZ-SCSI utility automatically configures the computer to use an Adaptec SCSI host adapter and the devices connected to it. The Adaptec EZ-SCSI utility also copies applications and device drivers to the computer's hard-disk drive. The configuration and installation process is explained with a series of screens. In most cases, the system and SCSI devices are configured to take full advantage of all the performance benefits of SCSI when you accept the default values suggested by these screens.

Follow these steps to install the Adaptec EZ-SCSI utility:

  1. If you have not already done so, create an Adaptec EZ-SCSI diskette for the version of NetWare you are using.
    Using the Dell Server Assistant CD  provides instructions for creating this diskette.

  2. Insert your Adaptec EZ-SCSI diskette into the diskette drive.

  3. Type dosinst and press <Enter>
    A message appears while the EZ-SCSI utility loads into memory.

  4. When the first EZ-SCSI screen appears, read the text carefully.
    You can press <F1> on any screen for additional help. Press <Esc> to exit a Help screen.

  5. Press <Enter> to continue with the installation.

  6. Follow the instructions that appear on the screen. Press <Enter> at every screen to accept the EZ-SCSI default values.
    If you accept all the default values, the EZ-SCSI utility copies the files from the diskette to the c:\scsi directory.
    The EZ-SCSI utility creates this directory if the directory does not already exist.
    The EZ-SCSI utility also adds command lines to your system 's configuration files (autoexec.bat and config.sys) that will load the required device drivers into memory when you boot your system .

  7. Press <Esc> to continue after the EZ-SCSI utility enters changes to your system configuration files.
    If you want to copy the files to a different directory or control the changes to your configuration files, follow the instructions on the screen. Press <F1> on any screen to see more information.

NOTE: If the EZ-SCSI utility is unable to locate the mscdex.exe file in the c:\dos directory, it will prompt for a pathname to access this file. Without this file, the utility cannot access the system 's CD-ROM drive.
  1. When the message (Adaptec EZ-SCSI has been successfully installed...)appears on the screen, press <Enter> or <Esc> to exit the EZ-SCSI utility, and remove the Adaptec EZ-SCSI diskette from the drive.
    Then reboot your system by pressing <Ctrl><Alt><Del>.

Installing NetWare 4.11 and Drivers

You need to install several updated drivers and Dell-supplied Novell patches when you install the NetWare 4.11 operating system on your system for the first time.

To install the NetWare 4.11 operating system on your PowerEdge system, use the .ham drivers that are provided on the Dell Server Assistant CD. You will need to create driver diskettes from the CD if you have not already done so. See the next section, "Creating the Netware 4.11 Driver Updates Diskette," for instructions on creating the driver diskettes from the Dell Server Assistant CD. For information about installing the .ham drivers in NetWare 4.11, see "Installing NetWare 4.11" found later in this document. To install the Dell-supplied Novell patches, see "Installing the Dell-Supplied Novell Patches" found later in this document.

NOTES: If the server has a redundant array of inexpensive disks (RAID) controller installed, you must set up the RAID controller and drives in a valid configuration before you perform the procedures in this section. Refer to the RAID controller documentation to configure the controller and drives, and then return to this section.

Before symmetric multiprocessing ( SMP) can be installed on your system, you must apply the IntraNetWare Support Pack 4.0A to the NetWare 4.11 operating system. See "Applying IntranetWare Support Pack 4.0A" found later in this document.

Creating the Netware 4.11 Driver Updates Diskette

To create a driver diskette from the Dell Server Assistant CD for driver installation purposes, perform the following steps:

  1. Insert the Dell Server Assistant CD into the server's CD-ROM drive and restart the system.

  2. When the Dell Server Assistant main menu appears, select Create Diskettes and press <Enter>.

  3. Select Create Operating Systems Support Diskettes and press <Enter>.

  4. Select the icon for your NetWare version and press <Enter>.

  5. Select Create Driver Diskette and press <Enter>, then select OK and press <Enter>.

  6. At the prompt, insert a blank diskette into the diskette drive, select OK, and press <Enter>.

  7. When the message The diskette was created successfully appears, select OK and press <Enter>, then select exit and press <Enter>.

  8. At the Exit Confirmation dialog box, remove the Dell Server Assistant CD and the newly created driver diskette, select OK, and press <Enter> to continue the system reboot.

NOTE: Remember to label the driver diskette; for example, label it NetWare 4.11 Driver Updates.

Preparing the Hard-Disk Drive for NetWare Installation

To prepare the hard-disk drive for NetWare installation, you must create a utility partition on the drive (if needed), create the primary MS-DOS partition, format the MS-DOS partition, install the c:\dos and c:\scsi subdirectories, and install certain system files.

You do not need to create a utility partition if you are installing NetWare 4.11 for the first time on your system. Dell shipped your system with the utility partition already created on the hard-disk drive; you can proceed to create the primary MS-DOS partition on the drive. If you are reinstalling NetWare 4.11, you will need to delete the utility partition and re-create it.

Using the following procedure, you can prepare the hard-disk drive using the Dell Server Assistant and Dell IntranetWare Support CDs.

If you do not need to create a utility partition on your hard-disk drive, go to step 2. Otherwise, perform the following steps to create a utility partition on your system:

  1. Insert the Dell Server Assistant CD into the server's CD-ROM drive and turn on (or reboot) the system.
  2. From the menu that appears, select Run System Utilities.
  3. From the Run System Utilities menu, select Create Utility Partition.
  4. At the Welcome... screen, select OK and press <Enter>.
  5. At the message Installation completed successfully, select OK and press <Enter>.
  6. Select Exit and press <Enter>.
  7. At the Exit Confirmation dialog box, remove the Dell Server Assistant CD, insert the Dell IntranetWare Support CD, select OK, and press <Enter> to reboot the server.
    If you have not already done so, insert the Dell IntranetWare Support CD into the server's CD-ROM and reboot the system.
    From the menu that appears, type 1 to select Create a Primary DOS Partition.
    At the next menu, type 2 to select Run FDISK in Automated Mode.
NOTE: Dell recommends running the fdisk utility in automated mode unless you need to specify a different size for the primary MS-DOS partition. Running the fdisk utility in automated mode creates a 25-MB partition.
  1. At the Warning... screen, read the information and type y to continue.
    The program partitions and then reboots the system.
  2. From the main menu that reappears, type 2 to select Format Primary DOS Partition.
    When prompted, type y and press <Enter> to proceed with the format.
  3. From the main menu that reappears, type 4 to select Recreate DOS System Files on HD.
  4. Read the message that appears and type y to continue.
  5. The message FILE TRANSFER COMPLETE appears briefly, and then you are returned to the main menu.
  6. Type q and press <Enter> to exit the utility, then remove the Dell IntranetWare Support CD from the drive, and press <Ctrl><Alt><Del> to reboot the system.
    Your hard-disk drive has been prepared for NetWare installation. Continue to the next subsection, Installing NetWare 4.11.

Applying IntranetWare Support Pack 4.0A

Before NetWare SMP can be installed in NetWare 4.11, you must apply IntranetWare Support Pack, 4.0A. The IntraNetWare Support Pack 4.0A is an MS-DOS executable patch file (iwsp4a.exe) that is available for download from Novell's World Wide Web site at www.novell.com. For complete instructions on applying IntraNetWare Support Pack 4.0A, refer to the Novell documentation.

To install the IntranetWare Support Pack 4. 0A complete these steps:

1. Place the Support Pack file onto a workstation that is attached to the PowerEdge server.

2. Copy the support pack file to a volume on the server.

3. Expand the file by typing iwsp4a.exe and press <Enter>.

4. Follow the directions listed in the iwsp4a.txt file included with the
support pack.

When Support Pack 4.0A has been applied, you can install SMP on your system.

Installing SMP Support

To add SMP support to your NetWare 4.11 installation, use the following procedure:

1. At the NetWare console prompt, type Load install and press <Enter>.

2. From the installation screen that appears, select Multi-CPU Options and press <Enter>.

3. From the selection screen, select Select a Platform Module and press <Enter>.

4. From the next selection screen, select MPS14.PSM and press <Enter>.

A confirmation screen appears asking if you want to load the selected module.

5. Select Yes and press <Enter>.

A message screen appears.

6. Exit the message screen, switch to the console prompt, down the server, and reboot the system to enable SMP support.

Using startup.ncf and autoexec.ncf

The startup.ncf and autoexec.ncf files contain a set of commands that are executed during the boot routine. The startup.ncf file contains commands to load the disk drivers. Once startup.ncf loads disk drivers, control is passed to the autoexec.ncf file to complete the boot routine. For additional information on the startup.ncf and autoexec.ncf files, refer to your NetWare documentation.

To automatically load the aic78u2.ham driver during the boot routine, the startup.ncf file must contain a load command line that specifies the location of the driver on the hard-disk drive. To find the slot number, type load a:\scsi\aic78u2.ham at the console prompt and press <Enter>. A list of slot numbers is displayed separated by commas. Press <Esc> to clear the command line.

NOTE: To load the driver from your hard-disk drive, the aic78u2.ham driver and nwaspi.cdm module must be copied from your NetWare 4.11 driver diskette to a directory on your hard-disk drive (usually, the server's start-up directory [for example, c:\nwserver]).

The syntax to load the aic78u2.ham driver follows:

load [pathname]\aic78u2.ham [options] slot=x

For example, the command line to load the driver from the c:\nwserver directory with the verbose= option on and a slot number of 10002 follows:

load c:\nwserver\aic78u2.ham verbose=y slot=10002

NOTE: For each Adaptec 78xx host adapter installed, a separate load command line must be included in the startup.ncf file. The slot number (slot=) identifies the specific adapter.

To modify the startup.ncf file, follow these steps:

1. Type install at the NetWare prompt, and press <Enter>.

2. Select the appropriate menu choice that allows you to edit the startup.ncf file.

3. Make the necessary changes. When you are finished, press <F10>.

Using Removable Media

The aha2940.ham driver module fully supports removable-media disk drives, including magneto-optical drives. Removable media is treated as a standard SCSI hard-disk drive, with some exceptions:

  • The driver only recognizes and registers media with 512 bytes/sector.
  • NetWare allows you to mount or dismount the media and lock or unlock the media.

These removable media options are supported by NetWare's monitor.nlm program.

Follow these steps to set up the removable media:

1. Load monitor.nlm to display the various options.

2. Select Disk Information.

All system hard-disk drives appear.

3. Select the removable-media device.

Drive status items appear as shown in Table 2.

Table 2. Drive Status Items

Menu Option

Default Value

Volume Segments on Drive1 Select for a list

2 Valid for removable media only

Verify Status

The Read After Write Verify option (menu option 2) is set to Hardware Level by default. This option cannot be specified in the startup.ncf or autoexec.ncf file. However, the default can be set on the command line.

The available options are defined in Table 3.

Table 3. Read After Writer Verify Options

Option Setting

Function

Disabled All writes to SCSI disk drives are executed with the SCSI Write command (0Ah or 2Ah).
Hardware Level All writes to SCSI disk drives are executed with the SCSI Write and Verify command (2Eh) or (if this command is not supported by the drive) with the SCSI Write command (0Ah or 2Ah), followed by the SCSI Verify command (2Fh).
Software Level Not supported.

Mount Status

Mounting causes a drive to come online as a NetWare storage device. Dismounted drives are inactive and cannot be accessed.

Before you eject your current media, you should first dismount it (using menu option 5). When the mount status is Dismounted, you can eject the media. However, NetWare does not allow you to dismount media that are locked.

To insert your new media, wait for the drive to spin up, and then select the Removable Drive Mount Status option.

Lock Status

If your removable-media device supports the lock/unlock feature, you can lock the media (using menu option 6). The media must be in the Not Locked state before you can eject it. If the media is locked, it cannot be ejected when you press the eject button.

Using Drives Tested and Approved for NetWare

To be fully certified as NetWare "Yes, Tested and Approved," a drive and host adapter must both pass a qualification process that takes place before you see the product. The goals of NetWare testing are to simplify installation and provide the highest quality disk subsystem.

Adaptec 78xx series host adapters and their drivers are fully tested and approved for NetWare. This means that you can purchase a NetWare drive (certified as "Yes, Tested and Approved") from a vendor, connect it to your system or host adapter, partition it, and create a volume without any compatibility concerns.

NOTE: Dell recommends using only Dell-tested drives.

Adaptec's aic78u2.ham driver module is flexible enough to allow you to connect SCSI drives that are tested and approved for NetWare as well as standard SCSI drives to a single host adapter. The driver registers each hard-disk drive accordingly.

Drive registration is a user-transparent process; no user interaction is required. You can tell that the drive has been detected as NetWare-tested and NetWare-approved if the message NetWare Yes Tested and Approved is included in the drive description string that appears when you run monitor.nlm (disk options).

Using the NetWare Tape Drive Utility

Included with NetWare is a server-based tape drive utility called sbackup.nlm. This allows backup of server disk drives to a server tape drive. The sbackup.nlm utility supports Adaptec host adapters. Use the following procedure to load the backup utility:

1. Load the SCSI adapter driver.

The syntax to load the aic78u2.ham driver follows:

load [pathname]\aic78u2.ham [options] slot=x

2. Refer to the Novell NetWare documentation for additional instructions on loading the server backup software. Refer to the NetWare Server Backup User's Guide
     to load the tsa and sbackup modules.

Setting Up a CD-ROM Drive With Net­Ware 4.11

To use a CD-ROM drive with NetWare 4.11, follow these instructions:

1. Load aic78u2.ham by entering the following command line:

load [pathname]\aic78u2.ham slot=x

2. Load nwaspi.cdm by entering the following command line:

load [pathname] nwaspi.cdm

NOTE: If nwaspi.cdm does not work, unload it and load it again. The first load initializes the host adapter; unloading and reloading allows the initialization to complete.

3. Load cdrom.nlm as follows:

load [pathname] cdrom.nlm

4. Enter the following line at the prompt, and then note the number and name of the CD that appears:

cd device list

5. Enter the number and volume name of the CD at the command line:

cd mount [number] [name]

The CD-ROM is now ready to be accessed as a volume.

Optimizing Performance

The Adaptec 78xx SCSI bus master firmware increases the SCSI performance of the Adaptec 78xx series host adapters under multitasking environments. The firmware uses a paging mechanism to handle up to 255 simultaneous SCSI commands. The sequencer can simultaneously manage up to 32 tagged, or 2 nontagged, SCSI commands for each SCSI device, up to a limit of 255 SCSI commands. The firmware can queue as many commands as the operating system is able to send to the host adapter. To set this feature, enter the following command:

max_tags=n

In general, a low number for the max_tags option gives better sequential performance. This value varies with the level of random disk accesses and drive characteristics.

NOTE: A large value for max_tags can cause starvation problems with some drives.

Troubleshooting for NetWare

Any error that occurs while the driver is initializing prevents it from loading. If an error does occur, the driver causes the system to beep and then display a numbered error message:

xxx message

The xxx indicates the error code, and message is a descriptive line describing the error. The error codes are divided into three categories:

  • 000-099 -- Non-host-adapter specific
  • 100-299 -- Host-adapter specific
  • 300-999 -- Reserved

Specific error codes, such as those in the following subsections, appear only if you have installed the host adapters and drivers that generate them:

Non-Host-Adapter Specific Error Codes

The following error codes alert you to error conditions caused by factors not related to the host adapter:

000 Failed ParseDriverParameters call

A call to NetWare's ParseDriverParameters routine has failed. The command-line contains errors, or you pressed <Esc> at the port or slot prompt.

001 Unable to reserve hardware, possible conflict

The driver failed in its attempt to reserve the host adapter's hardware settings (that is, direct memory access [DMA] and interrupt request [IRQ] settings). Another card in your system may be causing a conflict with the host adapter.

002 NetWare rejected card Failed AddDiskSystem call

The driver failed in its attempt to register the host adapter with NetWare. The file server may not have enough memory.

003 Invalid command line option entered > option

An invalid option was entered on the command line. The invalid option that was entered is also displayed.

004 Invalid command line, please enter correctly

The driver was unable to understand the command line options you entered. Be sure you have entered these options correctly.

Host-Adapter Specific

The following error codes alert you to error conditions caused by factors related to the host adapter:

200 No host adapter found for this driver to register

No Adaptec 78xx host adapter was found in your system for the driver to register. Be sure the host adapter is properly configured and properly seated in the slot.

203 Invalid 'device' setting

You have entered an invalid slot setting on the command line. You can only enter slot numbers for valid host adapters. If you load without the slot option, you will be prompted to enter a valid value.

204 Invalid 'verbose' setting, use 'y'

You can only enter y for this option (verbose=y).

205 Invalid 'removable' setting, use 'off'

You can only enter off for this option (removable=off).

206 Invalid 'fixed_disk' setting, use 'off'

You can only enter off for this option (fixed_disk=off).

208 SCSI present but not enabled/configured for PCI
