verify vdisk


Description	Analyzes redundant vdisks to find and fix inconsistencies between their redundancy data and their user data. This command applies to linear storage only. This command acts on all disks in a vdisk but not dedicated spares or leftover disks. This command will find and optionally 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). This command 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 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 is going bad. NOTE:The scrub vdisk command operates similarly to verify vdisk and can find media errors for any RAID level, including NRAID and RAID 0.
