Dell UCSA-901 Computer Hardware User Manual


 
Unable to rebuild a fault tolerant virtual disk
Issue: Cannot rebuild a fault tolerant virtual disk. For more information, see the alert log
for virtual disks.
Corrective
Action:
The replacement disk is too small or not compatible with the virtual disk. Replace
the failed disk with a compatible good physical disk with equal or greater capacity.
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 Performing A Manual Rebuild Of An Individual Physical Disk.
