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.

scrub vdisk
Description
Analyzes specified linear disk groups to find and fix disk errors. This command applies to linear
storage only.
This command acts on disks in a linear disk group but not dedicated spares or leftover disks. This
command will fix parity mismatches for RAID 3, 5, 6, and 50; find mirror mismatches for RAID 1 and
10; and fix media errors for all RAID levels.
Linear disk-group scrub can last over an hour, depending on disk-group size, utility priority, and
amount of I/O activity. However, a “foreground” 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 linear disk-group scrub (VRSC) job, use
the show vdisks command.
When a disk-group scrub job starts, event 206 is logged. When the scrub job ends, event 207 is
logged and specifies whether errors were found and whether user action is required.
