Troubleshooting

Physical Disk Failures and Rebuild Issues

Table 9-4 describes issues related to physical disk failures and rebuilds.

Table 9-4. Physical Disk Failure and Rebuild Issues

Issue

Corrective Action

Rebuilding the physical

disks after multiple disks

become simultaneously

inaccessible.

Multiple physical disk errors in a single array typically

indicate a failure in cabling or connection and could

involve the loss of data.
You can recover the virtual disk after multiple physical

disks become simultaneously inaccessible. Perform the

following steps to recover the virtual disk:

CAUTION:

Follow the safety precautions to prevent

electrostatic discharge.

1

Turn off the system, check cable connections, and reseat

physical disks.

2

Ensure that all the disks are present in the enclosure.

3

Turn on the system and enter the

<Ctrl><R>

utility

and import the foreign configuration. Press <F> at the

prompt to import the configuration, or press <C> to

enter the BIOS configuration utility and either import

or clear the foreign configuration.
If the virtual disk is redundant and transitioned to

Degraded state before going Offline, a rebuild operation

starts automatically after the configuration is imported.

If the virtual disk has gone directly to the Offline state

due to a cable pull or power loss situation, the virtual

disk is imported in its Optimal state without a

rebuild occurring.

You can use the BIOS Configuration Utility or

Dell OpenManage storage management application to

perform a manual rebuild of multiple physical disks.
For information on rebuilding a single physical disk,

see "Performing a Manual Rebuild of an Individual

Physical Disk" on page 111.
