Rebuilding a failed physical disk

Issue:

Rebuilding a physical disk that is in a failed state.

Corrective

If you have configured hot spares, the PERC card automatically tries to use one of

Action:

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 BIOS Configuration Utility (<Ctrl> <R>) or Dell OpenManage storage management application to perform a manual rebuild of an individual physical disk. For information on rebuilding a single physical disk, see Performing 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: The dedicated hot spare reverts to Ready state and the virtual disk goes to Failed state.

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.

Corrective

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.

Physical disk takes a long time to rebuild

Issue:A physical disk is taking longer than expected to rebuild.

Description: A physical disk takes longer to rebuild when under high stress. For example, there is one rebuild I/O operation for every five host I/O operations. You cannot add a second virtual disk to a disk group while the virtual disk in that disk group is undergoing a rebuild. The firmware does not allow you to create a virtual disk using the free space available in a disk group if a physical disk in a virtual disk group is undergoing a rebuild operation.
