Installing the autoloader consists of the following steps, which are explained in more detail later in this section:
Before you install your new Dell PowerVault 124T DLT VS160 autoloader, unpack it carefully and inspect it for any damage that might have occurred during shipping. The Getting Started Guide included in the packaging describes all the necessary information to unpack and inspect your autoloader correctly. Locate the Getting Started Guide and follow the directions.
Ensure that the work area is free from conditions that could cause electrostatic discharge (ESD). Discharge static electricity from your body by touching a known grounded surface, such as your computer's metal chassis.
You must connect the Dell PowerVault 124T DLT VS160 autoloader to one of the following SCSI bus types:
 |
NOTE: The Dell PowerVault 124T DLT VS160 autoloader is not compatible with a High-voltage Differential (HVD) SCSI bus. |
Your SCSI host adapter card must also support the SCSI bus type used to connect the autoloader. If you use a LVD SCSI bus, use a host adapter card with a connection for a high-density (HD) 68-pin cable.
|
NOTE: If you use an SE SCSI bus, the tape drive's performance is limited to the maximum data transfer speed of the bus. |
|
NOTE: The maximum number of autoloaders supported per SCSI bus is two. |
|
NOTE: The autoloader may not work with multiple SCSI LUNS when attached to a redundant array of independent disks (RAID) controller. The autoloader is not recommended for use with a RAID controller. If this problem occurs, it is recommended that the autoloader be attached to a separate SCSI bus controller on the server. |
The following accessories are shipped with the Dell PowerVault 124T DLT VS160 autoloader:
Choose a location that meets the following criteria (see "Technical Specifications"):
 |
NOTICE: Do not place the autoloader on its side or upside down. Do not stack anything on top of the autoloader. |

Elevated Operating Ambient Temperature |
When installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than the room ambient. You must install the equipment in an environment compatible with the manufacturer's maximum recommended ambient temperature. | |
Reduced Air Flow |
Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised. |
|
Mechanical Loading |
Mounting of the equipment in a rack should be such that a hazardous condition is not achieved due to uneven mechanical loading. |
|
Overloading the Circuit |
Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing the concern. | |
Reliable Grounding |
Reliable grounding of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit, such as use of power strips. |
Your autoloader is equipped with a bar code reader. The bar code reader is enclosed within the body of the autoloader and automatically scans each cartridge in the magazine upon power up, after a reset, after an import or export, or when a re-inventory command is issued (see "Running an Inventory"). The information from each label is stored in memory and available through SCSI and the Remote Management Unit to the computer's operating system or backup application upon request. The barcode reader can be disabled through the operator control panel or the web user interface. This feature allows faster initialization of the unit if non-bar code labels or no lables are used on the cartridges.
If utilizing the bar code reader, you must insert bar code labels into the slide-in slot on the front of each cartridge. The labels must conform to ANSI/AIM BC1 -1995 Uniform Symbology Specification Code 39. A set of bar code labels is initially included with the autoloader. Refer to www.dell.com for information on obtaining additional bar code labels.

NOTE: If the cover must be taken off, there are 26 screws and 6 rail bolts that need to be removed. The cover should be removed only by a qualified Dell Service Provider. |
Before you begin, clear a desk or table so that you can unpack the autoloader. You also need to select an open 2U computer rack location near the server that will host the autoloader.
|
NOTICE: If the room in which you are working differs from the temperature in which the autoloader was shipped or stored by 15°C (30°F) or more, let the autoloader acclimate to the surrounding environment for at least 12 hours before opening the shipping carton. |
Unpack and inspect the autoloader for shipping damage by doing the following:
Clear a table or desk so that you have room to unpack the autoloader.
Inspect the shipping box for damage. If you notice any damage, report it to the shipping company immediately.
Open the shipping box and remove the accessories package. Set the accessories package aside for now.
Lift the autoloader and padding out of the box and place it on the work surface, top facing up. Do not set the autoloader on either end or sides.
Carefully remove the shipping padding from the front and back of the autoloader. Then remove the bag from the autoloader. Save the packing materials in case you need to move or ship the autoloader in the future. Illustrations on the box flaps indicate the proper placement of the packaging materials.

To connect the SCSI and power cables to the autoloader, follow these steps:
Shut down and turn off the selected server. Turn off all attached accessory devices, such as printers and other SCSI devices.
Attach one end of the SCSI cable (included in the accessory kit) to one of the connectors on the back panel of the autoloader.
Attach the other end of the SCSI cable to the connector on the SCSI host adapter or to the connector on the previous device on the SCSI bus.
If the supplied SCSI cable does not fit the connector on your SCSI host adapter, you either have an incompatible SCSI host adapter or you need to purchase a cable adapter. Contact your service representative or your SCSI host adapter manufacturer for information.
| 1 | Ethernet cable | |
| 2 | SCSI cable | |
| 3 | SCSI terminator |
Attach the terminator to the remaining SCSI connector on the back panel of the autoloader (if the autoloader is the last or only device on the SCSI bus). Otherwise, attach the cable to the next device on the SCSI bus. Make sure that the last device on the SCSI bus is properly terminated.
Attach the female connector of the power cable to the power connector on the back panel of the autoloader.
Plug in the power cable to the nearest properly grounded power outlet.
Plug in the host server or workstation and all attached devices.
Turn on the autoloader by setting the power switch on the back panel to the ON position. Turn on any other devices you turned off earlier. Check the LCD screen to make sure the autoloader is receiving power. If it is not, check the power connections and your power source.
During the Power-on Self-Test (POST), both LEDs are illuminated briefly, followed by only the Ready/Activity LED flashing. When the initialization sequence is complete, the LCD screen displays the Home screen.
Turn on the server.
If necessary, install a SCSI host adapter, software, and compatible drivers. Refer to the manuals for the host computer and SCSI host adapter for detailed instructions. In addition, follow these general guidelines:
When the host server is powered on, install software, and/or drivers that are compatible with the autoloader (see "Installing the Device Drivers"). Software compatibility information is available at support.dell.com. Most backup software packages require an additional module to communicate with the autoloader robotics.
If the host server is connected to a network, check with the system administrator before turning off power.
Use proper procedures to prevent electrostatic discharge (ESD). Use wrist-grounding straps and anti-static mats when handling internal components.
Make sure that the host server has an open expansion slot.
Make sure that your backup application supports the SCSI host adapter.
Depending on the server configuration, you may need to change the SCSI ID of the autoloader (see "Setting the SCSI ID").
Ensure the autoloader is properly terminated. If the autoloader is the only SCSI device—other than the SCSI host adapter—on the selected SCSI bus, it must be terminated. Likewise, if the autoloader is physically the last SCSI device on the SCSI bus, it must be terminated. Only the devices physically at the beginning and end of the SCSI bus should be terminated. If the host is located at the beginning of the SCSI bus, the host should already have a terminator installed.
Verify the connection between the autoloader and host by going to Settings>Control Panel>System>Hardware>Device Manager>Tape Drive and/or Media Changer in Microsoft® Windows® 2000, Microsoft Windows XP and Windows Server® 2003. For more information on verifying the connection of SCSI devices, consult the operating system documentation.
There are two device drivers associated with the Dell PowerVault 124T DLT VS160 autoloader. One for the autoloader itself, and a second for the DLT VS160 tape drive within the autoloader.

To verify the detection of a tape drive, administrators should check for its entry in /proc/scsi/scsi. Current versions of Linux may not scan the logical storage unit (LUN) ID of every device. This can result in some PowerVault devices not being identified or listed in the /proc/scsi/scsi output. Administrators can follow these steps to enable support for such devices.
Type cat/proc/scsi/scsi. The output will look similar to the following:
Attached devices:echo "scsi-add-single-device H C I L">/proc/scsi/scsi
H C I L refers to the nexus described in step 2. So, with the PowerVault 124T robot configured at LUN 1, type:
echo "scsi-add-single-device 3 0 0 1">/proc/scsi/scsiThe echo command will force a scan of each device at the given nexus.
Type cat /proc/scsi/scsi again to verify that all devices are now listed. The output will look similar to the following:
Attached devices:Attached devices:
Host: scsi3 Channel: 00 Id: 00 Lun: 01
Vendor: DELL Model: PV-124T Rev:
V31
Type: Sequential-Access ANSI
SCSI revision: 03
Administrators should add the echo command to the Linux boot scripts because the device information is not persistent and must be created each time the system boots up. One example file that can be used for storing the commands is /etc/rc.local. Note that configuring additional devices on a server or a storage area network (SAN) can cause the devices to be reordered, which requires administrators to modify the commands. If the Fibre Channel adapter supports Persistent Bindings or an equivalent function, it can be enabled to reduce the chance of devices being reordered upon discovery.
|
NOTE: This procedure must be run each time the server is booted. Also, if backup application services are running (for example, they automatically start when the OS loads), they must be disabled and re-enabled after the above procedure. |
The other way to enable LUN support is to recompile the kernel and enable LUN scanning in the Adaptec driver, but it requires advanced knowledge of Linux and will not be covered here. However, it will allow the server to always boot and see the device without any manual procedures.
From the System Console, verify the LUN device is not being detected by using the list storage adapters command.
Typical output where only the tape drive is being recognized:
0x08 [V321-A3] Adaptec SCSI Card 39160/3960D – Ultra160 SCSI [slot 201]From the System Console, type nwconfig.
Select NCF files Options from the Configuration Options screen.
Select Edit STARTUP.NCF from the Available NCF Files Options screen.
Add the /LUNS switch to the load line of the appropriate SCSI driver. If a dual channel card is installed and the user is unsure which channel the LUN device is attached to, simply edit both lines.
LOAD ADPT160M.HAM SLOT=201 /LUNSAfter the STARTUP.NCF file has been edited, save the file and reboot the server to activate the new STARTUP.NCF.
Upon reboot navigate to the System Console and type scan all. This will start a scan of all the LUNS on each adapter.
When the scan is complete, verify the LUN device has been detected using the list storage adapters command.
Typical output with both the tape drive and loader being recognized:
0x08 [V321-A3] Adaptec SCSI Card 39160/3960D – Ultra160 SCSI [slot 201]Netware may display unbound device, meaning a driver is not bound to the loader unless a driver from a backup software is loaded. This does not prevent the backup application from detecting the LUN and binding the appropriate driver.
|
NOTE: The user must type the command scan all upon OS boot every time. If backup software services automatically start on OS boot, the user must disable them, run the scan all command, and re-enable the services. |
|
NOTE: Netware may display unbound device meaning a driver is not bound to the loader unless a driver from a backup software is loaded. This does not prevent the backup application from detecting the LUN and binding the appropriate driver. |
