Scrub Vdisk - HP P2000 Reference Manual

scrub vdisk

Description Analyzes specified vdisks to detect, report, and store information about disk defects. Vdisk-level
errors reported include: hard errors, media 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
When the scrub is complete, an event with code 207 is logged that specifies whether errors were
found. For details, see the Event Descriptions Reference Guide.
