Multiple disks are inaccessible
Issue: Multiple disks are simultaneously inaccessible.
Probable Cause: Multiple physical disk errors in a single array typically indicate a failure in cabling or connection and could
involve the loss of data.
Corrective
Action:
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 HII Configuration Utility.
4. Import the foreign configuration.
5. Press <F> at the prompt to import the configuration, or press <C> to enter the HII 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.
NOTE: You can use the HII Configuration Utility or Dell OpenManage storage management application to perform a
manual rebuild of multiple physical disks.
Rebuilding data for a failed physical disk
Issue:
Rebuilding data for a physical disk that is in a failed state.
Probable Cause: Physical disk is failed or removed.
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.
NOTE: You can use the HII Configuration Utility or Dell OpenManage storage management application to perform a
manual rebuild of an individual physical disk.
Virtual disk fails during rebuild using a global hot spare
Issue:
A virtual disk fails during rebuild while using a global hot spare.
Probable Cause: One or more disks in the virtual disks fails or is disconnected while the rebuild is in progress.
Corrective
Action:
No action is required. The global hot spare reverts to Hot spare state and the virtual disk is in Failed
state.
Dedicated hot spare disk fails during rebuild
Issue:
A hot spare disk fails during rebuild while using a dedicated hot spare.
Probable Cause: The dedicated hot spare assigned to the virtual disk fails or is disconnected while the rebuild is in
progress.
Corrective
Action:
If there is a global hot spare available with enough capacity, rebuild will automatically start on the global
hot spare. Where there is no hot spare present, you must insert a physical disk with enough capacity into
the system before performing a rebuild.
