132 Alphabetical list of commands
scrub vdisk
Description Analyzes specified vdisks to find and fix disk errors. This command acts on disks in a vdisk but not
dedicated spares or leftover disks. This command will fix parity mismatches for RAID 3, 5, 6, and
50; mirror mismatches for RAID 1 and 10; and media errors for all RAID levels.
Vdisk scrub can last over an hour, depending on vdisk 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 job-parameters command. You can use a vdisk while it is
being scrubbed. To check the progress of a vdisk scrub (VRSC) job, use the show vdisks command.
When a vdisk scrub operation starts, event 206 is logged. When a vdisk scrub operation ends,
event 207 is logged and specifies whether errors were found and whether user action is required.
