Fatal error or data corruption reported

Issue: Fatal error(s) or data corruption(s) are reported when accessing virtual disks.

Corrective Action: Contact Dell Technical Support.

Physical disk displayed as blocked

Issue: One or more physical disks is displayed as Blocked and cannot be configured.

Corrective Action: Update the PERC cards to the latest firmware available on dell.com/support.

Multiple Disks Become Inaccessible

Issue: Rebuilding the physical disks after multiple disks become simultaneously

inaccessible.

Corrective Action: 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 BIOS Configuration Utility (<Ctrl> <R>) utility.

4. Import the foreign configuration.

5. Press <F> at the prompt to import the configuration, or press <C> to enter the BIOS Configuration

Utility (<Ctrl> <R>) 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.

NOTE: You can use the BIOS Configuration Utility (<Ctrl> <R>) or Dell OpenManage storage

management application to perform a manual rebuild of multiple physical disks. For information on

rebuilding a single physical disk, see the topic Performing A Manual Rebuild Of An Individual

Physical Disk.

Rebuilding A Failed Physical Disk

Issue: Rebuilding a physical disk that is in a failed state.

Corrective Action: If you have configured hot spares, the PERC card automatically tries to use one of

the hot spares to rebuild a physical disk that is in a failed state. Manual rebuild is

necessary if no hot spares with enough capacity to rebuild the failed physical disks

are available. You must insert a physical disk with enough storage in the subsystem

before rebuilding the physical disk.
