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

Action:

rebuild a physical disk that is in a failed state. The automatic rebuild will not be available if

there is no hot spare with enough capacity to rebuild the failed physical disk. You must make

sure a physical disk with enough storage in the subsystem is set as a hot spare for rebuilding

the 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 goes back to Hotspare state and the virtual disk goes to Failed state.

Issue:

A virtual disk fails during rebuild while using a dedicated hot spare.

Description:

The dedicated hot spare goes to Ready state and the virtual disk goes to Failed state.

Issue:

A virtual disk fails during rebuild while using a dedicated hot spare.

Description:

The dedicated hot spare goes to Ready state and the virtual disk goes to Failed state.

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.

Self Monitoring and Reporting Technology (SMART) monitors the internal performance of all motors, heads, and

physical disk electronics and detects predictable physical disk failures.

NOTE: For information about where to find reports of SMART errors that can indicate hardware failure, see the

Chassis Management Controller for Dell PowerEdge VRTX User's Guide at dell.com/esmmanuals.

Issue:

A SMART error is detected on a physical disk in a redundant virtual disk.
