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 106 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
