scrub disk-groups
Description
Analyzes specified disk groups to find and fix errors.
This command acts on disks in a disk group but not dedicated spares or leftover disks. The command will fix
parity mismatches for ADAPT and for RAID 5 and RAID 6, as well as for linear disk groups utilizing RAID 3 and
RAID 50; find but not fix mirror mismatches for RAID 1 and 10; and fix media errors for all RAID levels.
Disk-group scrub can last over an hour, depending on disk-group size, utility priority, and amount of I/O
activity. However, a manual scrub performed with this command is typically faster than a background scrub
enabled with the set advanced-settings command. You can use a disk group while it is being scrubbed. To
check the progress of a disk-group scrub (VRSC) job, use the show disk-groups command.
When a disk-group scrub job starts, event 206 is logged. When a scrub job ends, event 207 is logged and
specifies whether errors were found and whether user action is required.
