Dell Shared PowerEdge RAID Controller (PERC) 8 For Dell PowerEdge VRTX Systems User’s Guide
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:
- Turn off the system, check the cable connections, and reseat the physical disks.
- Ensure that all the disks are present in the enclosure.
- Turn on the system and enter the Chassis Management Controller (CMC).
- 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.
