Dell PowerVault ME4 Series Storage System CLI Guide

scrub vdisk


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