Abort a disk group verification
Perform the following steps to abort a disk group verification:
1. In the Pools topic, select the pool for the disk group that you are verifying in the pools table.
2. Select the disk group in the Related Disk Groups table.
3. Select Action > Disk Group Utilities.
The Disk Group Utilities panel opens, showing the current job status.
4. Click Abort Verify.
A message confirms that verification has been aborted.
5. Click OK.
Scrubbing a disk group
The system-level Disk Group Scrub option automatically checks all disk groups for disk defects. If this option is disabled, you can
still perform a scrub on a selected disk group. A scrub analyzes the selected disk group to find and fix disk errors. A scrub also
fixes parity mismatches for RAID 3, 5 and 6 and ADAPT and mirror mismatches for RAID 1 and 10.
A scrub can last over an hour, depending on the size of the disk group, the utility priority, and the amount of I/O activity.
However, a manual scrub is typically faster than a background scrub. You can use a disk group while it is being scrubbed. When
a scrub is complete, event 207 is logged and specifies whether errors were found and whether user action is required.
Scrub a disk group
1. In the Pools topic, select the pool for the disk group that you plan to scrub in the pools table.
2. Select the disk group in the Related Disk Groups table.
3. Select Action > Disk Group Utilities. The Disk Group Utilities panel opens, showing the current job status.
4. Click Scrub Disk Group. A message confirms that the scrub has started.
5. Click OK. The panel shows the scrub's progress.
Abort a disk group scrub
1. In the Pools topic, select the pool for the disk group that you are verifying in the pools table. Then, select the disk group in
the Related Disk Groups table.
NOTE:
If the disk group is being scrubbed but the Abort Scrub button is grayed out, a background scrub is in progress.
To stop the background scrub, disable the Disk Group Scrub option as described in Configuring system utilities.
2. Select Action > Disk Group Utilities. The Disk Group Utilities panel opens, showing the current job status.
3. Click Abort Scrub. A message confirms that the scrub has been aborted.
4. Click OK.
