Problem

Suggested Solution

Some operating systems do not load in a computer with a PERC 2/DC adapter.

Check the system BIOS configuration for PCI interrupt assignments. Make sure a unique interrupt is assigned for PERC 2/DC. Initialize the logical drive before installing the operating system.

One of the hard drive in the array fails often.

Check the SCSI cables.

Pressed <Ctrl> <M>. Ran Dellconf.exe and tried to make a new configuration. The system hangs when scanning devices.

Replace the drive cable.

Multiple drives connected to PERC 2/DC using the same power supply. There is a problem spinning the drives all at once.

Set the drives to spin on command. This will allow PERC 2/DC to spin two devices simultaneously.

Pressing <Ctrl> <M> or running Dellconf.exe does not display a menu.

These utilities require a color monitor.

At system power-up with the PERC 2/DC installed, the PERC 2/DC BIOS banner display is garbled or does not appear at all.

PERC 2/DC cache memory may be disabled or missing.

Cannot flash or update the EEPROM.

Contact Dell support.

appears and remains on the screen.

Why does a failed logical array still get a drive assignment?

To maintain the DOS Path statement integrity.

Problem

Suggested Solution

Adapter BIOS Disabled. No Logical Drives Handled by BIOS

The PERC 2/DC BIOS is disabled. Sometimes the BIOS is disabled to prevent booting from the BIOS. This is the default when cluster mode is enabled.

Enable the BIOS by pressing <Ctrl> <M> at the boot prompt to run the PERC 2/DC BIOS Configuration utility.

Host Adapter at Baseport xxxx Not Responding

The BIOS cannot communicate with the adapter firmware.

Make sure PERC 2/DC is properly installed. Check SCSI termination and cables.

No PERC 2/DC Adapter

The BIOS cannot communicate with the adapter firmware.

Make sure PERC 2/DC is properly installed.

Press any key to run the Configuration Utility.

The configuration stored in the PERC 2/DC adapter does not match the configuration stored in the drives.

Press a key to run PERC Configuration Manager. Choose View/Add Configuration from the Configure menu. Choose View/Add Configuration to examine both the configuration in NVRAM and the configuration stored on the disk drives. Resolve the problem by selecting one of the configurations.

Clear the configuration. Low level format the related drives and re-create the configuration.

1 Logical Drive Failed

A logical drive failed to sign on.

Make sure all physical drives are properly connected and are powered on. Run PERC Configuration Manager to find out if any physical drives are not responding. Reconnect, replace, or rebuild any drive that is not responding.

X Logical Drives Degraded

x number of logical drives signed on in a degraded state.

Make sure all physical drives are properly connected and are powered on. Run PERC Configuration Manager to find if any physical drives are not responding. Reconnect, replace, or rebuild a drive that is not responding.

1 Logical Drive Degraded

A logical drive signed on in a degraded state.

Make sure all physical drives are properly connected and are powered on. Run PERC Configuration Manager to find out if any physical drives are not responding. Reconnect, replace, or rebuild any drive that is not responding.

Insufficient memory to run BIOS. Press any key to continue�

Not enough PERC 2/DC memory to run PERC 2/DC BIOS.

Make sure PERC 2/DC cache memory has been properly installed.

Insufficient Memory

Not enough memory on the PERC 2/DC adapter to support the current configuration.

Make sure PERC 2/DC cache memory has been properly installed.

Channel x:a.b.c

The physical drives with SCSIO IDs a, b, and c are not responding on SCSI channel x.

Make sure the physical drives are properly connected and are powered on.

Suggested Solution

Following SCSI disk not found and no empty slot available for mapping it

The physical disk roaming feature did not find the physical disk with the displayed SCSI ID. No slot is available to map the physical drive. PERC 2/DC cannot resolve the physical drives into the current configuration.

Reconfigure the array.

Channel x: a, b, c

The physical drive roaming feature found the same data on two or more physical drive on channel x with SCSI IDs a, b, and c. PERC 2/DC cannot determine the drive that has the duplicate information.

Remove the drive or drives that should not be used.

Unresolved configuration mismatch between disks and NVRAM on the adapter

The configuration stored in the PERC 2/DC NVRAM does not match the configuration stored on the drives.

Press a key to run PERC Configuration Manager. Choose View/Add Configuration from the Configure menu. Choose View/Add Configuration to examine both the configuration in NVRAM and the configuration stored on the disk drives. Resolve the problem by selecting one of the configurations.

Information

Physical Drive Errors

To display the PERC Configuration Manager Media Error and Other Error options, press <F2> after selecting a physical drive under the Physical Drive menu, selected from the Objects menu. A media error is an error that occurred while actually transferring data. An Other Error is an error that occurs at the hardware level because of a device failure, poor cabling, bad termination, signal loss, etc.

Virtual Sizing

The Virtual Sizing option enables RAID expansion. Virtual sizing must be enabled to increase the size of a logical drive or add a physical drive to an existing logical drive. Run PERC Configuration Manager by pressing <Ctrl> <M> to enable Virtual Sizing. Select the Objects menu, then select the Logical Drive menu. Select View/Update Parameters. Set Virtual Sizing to Enabled.

PERC 2/DC Power Requirements

The Maximum PERC 2/DC power requirements are 15 watts at 5V and 3 Amps.

Refer to Chapter 10 Installing Windows NT Drivers for installation information.
