HP StorageWorks 2300 Modular Smart Array CLI reference guide 75

scrub vdisk

Description Analyzes specified vdisks to detect, report, and store information about disk defects. Vdisk-level

errors reported include: hard errors, medium errors, and bad block replacements (BBRs). Disk-level

errors reported include: metadata read errors, SMART events during scrub, bad blocks during scrub,

and new disk defects during scrub.

For RAID 3, 5, 6, and 50, scrub checks all parity blocks to find data-parity mismatches. For RAID 1

and 10, scrub compares the primary and secondary disks to find data inconsistencies. For NRAID

and RAID 0, scrub checks for media errors.

A scrub can last over an hour, depending on vdisk 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 job-parameters command.

When the scrub is complete, the number of errors found is reported with event code 207 in the event

log. You can use a vdisk while it is being scrubbed.

Parameters vdisks

Names or serial numbers of the vdisks to scrub.
