verify vdisk Description Analyzes redundant vdisks to find and fix inconsistencies between their redundancy data and their user data. This command acts on disks that are associated with a vdisk and are neither dedicated spares nor leftovers. This command will fix parity mismatches for RAID 3, 5, 6, and 50, and mirror mismatches for RAID 1 and 10. This command can be performed only on a vdisk whose status is FTOL (fault tolerant and online); it cannot be performed for NRAID or RAID 0. Verification can last over an hour, depending on vdisk size, utility priority, and amount of I/O activity. You can use a vdisk while it is being verified. To view the progress of a vdisk verify (VRFY) job, use the show vdisks command. When verification is complete, event 21 is logged and specifies the number of inconsistencies found. Such inconsistencies can indicate that a disk in the vdisk is going bad. TIP: Unless you want to verify without fixing errors, it is better to use the scrub vdisk command, which operates similarly to verify vdisk and also can find and fix media errors for any RAID level, including NRAID and RAID 0. Syntax verify vdisk vdisks [fix yes|no] Parameters vdisks A comma-separated list of the names or serial numbers of the vdisks to verify. For vdisk syntax, see "Command syntax" (page 20). fix yes|no Optional. Specifies whether or not to automatically fix parity mismatches by making parity match the data in all cases. If you specify no, event 21 will report any errors found and they will not be fixed. The default is yes. Example Start verifying vdisk vd1: # verify vdisk vd1 Info: The verify was started on vdisk vd1. (vd1) (2012-01-20 17:08:33) Success: Command completed successfully.
