verify disk-groups
Description
Analyzes redundant disk groups to find and fix inconsistencies between their redundancy data and their user
data.
This command acts on all disks in a disk group but not dedicated spares or leftover disks. This command will
find and optionally fix parity mismatches for RAID 3, 5, 6, and 50, and find mirror mismatches for RAID 1 and
10. This command can be performed only on a disk group whose status is FTOL (fault tolerant and online).
This command cannot be performed for NRAID or RAID 0.
Verification can last over an hour, depending on disk-group size, utility priority, and amount of I/O activity.
You can use a disk group while it is being verified. To view the progress of a verify (VRFY) job, use the show
disk-groups command.
When verification is complete, event 21 is logged and specifies the number of inconsistencies found. Such
inconsistencies can indicate that a disk is going bad.
NOTE: The scrub disk-groups on page 102 command operates similarly to verify disk-groups
and can find media errors for any RAID level, including NRAID and RAID 0.

Syntax
verify disk-groups
[fix yes|no]
disk-groups
Parameters
fix yes|no
Optional. Specifies whether or not to automatically fix parity mismatches by making parity match the data in
all cases. The default is no. This parameter does not pertain to mirror mismatches, which are never
automatically fixed because the system does not know which disk contains the "good" data.
disk-groups
A comma-separated list of the names or serial numbers of the disk groups to verify. A name that includes a
space must be enclosed in double quotes.
Examples Start verifying disk group dg1.
# verify disk-group dg1
