Dell EMC H745P MX - Rebuilding a Failed Physical Disk; Virtual Disk Fails During Rebuild Using a Global Hot Spare; Virtual Disk Fails During Rebuild Using a Dedicated Hot Spare; Physical Disk Fails During Reconstruction on Redundant Virtual Disk

If the virtual disk is redundant and transitioned to Degraded state before going Oine, a rebuild operation starts automatically after the
conguration is imported. If the virtual disk has gone directly to the Oine 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 Conguration Utility or Dell OpenManage storage management application to perform a manual
rebuild of multiple physical disks.
Rebuilding a failed physical disk
Issue: Rebuilding a physical disk that is in a failed state.
Corrective Action: If you have congured 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 Conguration 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.
Description: The global hot spare reverts to Hotspare state and the virtual disk is in Failed state.
Virtual disk fails during rebuild using a dedicated hot spare
Issue:
A virtual disk fails during rebuild while using a dedicated hot spare.
Description: You must manually rebuild or add a new drive to system and start rebuilding.
Physical disk fails during reconstruction on redundant virtual
disk
Issue:
A physical disk fails during a reconstruction process on a redundant virtual disk that has a hot spare.
Description: The dedicated hot spare reverts to Ready state and the virtual disk goes to Failed state.
Virtual disk fails rebuild using a dedicated hot spare
Issue:
A virtual disk fails during rebuild while using a dedicated hot spare.
Description: The dedicated hot spare is in Ready state and the virtual disk is in Failed state.
