Check Consistency report
The check consistency report provides information on all the consistency checks performed on the controller in a chronological order. It
provides information such as last run time and result. If the consistency check fails, it provides the reason for the failure.
Performing a Check Consistency
The Check Consistency task verifies the accuracy of the redundant (parity) information. This task only applies to redundant virtual disks.
When necessary, the Check Consistency task rebuilds the redundant data. If the virtual disk is in a Failed Redundancy state, running a
check consistency may return the virtual disk to a Ready state.
Performing Check Consistency using OMSA
The link below provides information on how to perform Check Consistency using OpenManage Server Administrator (OMSA):

Canceling a Check Consistency
The Cancel Check Consistency task stops a check consistency operation while it is in progress.
Pausing a Check Consistency
The Pause Check Consistency task pauses a check consistency while it is in progress.
NOTE:
The Pause Check Consistency task updates the virtual disk State property to Resynching Paused immediately.
The Progress property may continue to increment for up to three seconds. This time delay occurs because the polling
task may take up to three seconds to query the task information and update the display.
Resuming a Check Consistency
The Resume Check Consistency task resumes check consistency after it has been paused.

Virtual disk troubleshooting
Rebuilding of virtual disk does not work
Rebuilding of virtual disk does not work in the following situations:
• The virtual disk is non redundant — For example, a RAID 0 virtual disk cannot be rebuilt because RAID 0 does not provide data
redundancy.
• There is no hot spare assigned to the virtual disk — As long as the virtual disk is redundant, to rebuild it:
○ Remove the failed physical disk and replace it. A rebuild automatically starts on the new disk.
○ Assign a hot spare to the virtual disk and then perform a rebuild.
• You are attempting to rebuild onto a hot spare that is too small — Different controllers have different size requirements for hot
spares.
