The verification process checks whether the redundancy data in the virtual disk is
consistent with the user data in the virtual disk. The number of inconsistencies
found is noted in the “Vdisk verification complete” event (event code 21) in the
event log. Such inconsistencies can indicate that a drive in the virtual disk is going
bad. For information about identifying a failing drive, see “Enabling or Disabling
SMART Changes” on page 137.
The number of virtual disk verifications you can initiate is determined by the
current load on your controllers. If an error is displayed when you try to verify a
virtual disk and multiple utilities running, wait until those utilities have completed
and try again.
Starting Virtual Disk Verification
To verify a virtual disk:
1. Select Manage > Virtual Disk Config > Vdisk Configuration > Verify Virtual Disk.
For each virtual disk, the virtual disk panel shows a status icon; the name, RAID
level, size, number of disk drives, and number of volumes; and utility status, if any.
2. Select the virtual disk to verify.
3. Click Verify Virtual Disk Parity.
Verification begins and the percentage of verification completed is displayed. You
can continue to use the virtual disk during verification. To check the progress of the
verification, select Manage > Virtual Disk Config > Vdisk Utility Progress.
Stopping Virtual Disk Verification
You can stop the virtual disk verification process at any time. If you stop
verification, you cannot resume; you must restart the verification from the
beginning.
1. Select Manage > Virtual Disk Config > Abort A Vdisk Utility.
For each virtual disk, the virtual disk panel shows a status icon; the name, RAID
level, size, number of disk drives, and number of volumes; and utility status, if any.
2. Select the virtual disk to stop verifying.
3. Click Abort Verify.
When processing is complete, the virtual disk icon changes to show that no utility is
running.
