Fatal Error Or Data Corruption Reported
Issue: Fatal error(s) or data corruption(s) is reported when accessing virtual disks.
Corrective
Action:
Contact Dell Technical Support.
Physical Disk Displayed As Blocked By Management Application
Issue: One or more physical disks are displayed as Blocked and cannot be configured.
Corrective
Action:
Ensure the physical disk is supported by SCSI-3 Persistent Reservation (PR). Update
the physical disk and Shared PERC 8 to the latest firmware available on dell.com/
support.
NOTE: If you are using the Dell Update Package (DUP) to update the physical disk, shutdown all the
server modules and power cycle the chassis after the update is completed.
Multiple Disks Become Inaccessible
Issue: Multiple disks become simultaneously inaccessible.
Corrective
Action:
Multiple physical disk errors in a single array indicate a failure in cabling or
connection and can involve loss of data. Perform the following steps to recover the
virtual disk:
CAUTION: Follow the safety precautions to prevent electrostatic discharge.
1. Turn off the system, check the cable connections, and reseat the physical
disks.
2. Ensure that all the disks are present in the enclosure.
3. Turn on the system and enter the Chassis Management Controller (CMC).
4. Use the CMC to import the foreign configuration that is detected or clear the
foreign configuration.
NOTE: For information about importing or clearing foreign configuration, see
the Dell Chassis Management Controller for Dell PowerEdge VRTX User’s
Guide at dell.com/poweredgemanuals.
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.
Rebuilding A Failed Physical Disk
Issue: Rebuilding a physical disk after one of them is in a failed state.
Corrective
Action:
If you have configured hot spares, the Shared PERC 8 card automatically tries to
rebuild a physical disk that is in a failed state. The automatic rebuild is not available
if there is no hot spare with enough capacity to rebuild the failed physical disk. You
