show volumes

clear disk-metadata

Description Clears metadata from leftover disks. For a leftover disk, the show disks command shows the Usage

value LEFTOVR.

CAUTION: Only use this command when all disk groups are online and leftover disks exist.

Improper use of this command may result in data loss.

NOTE: If you are uncertain whether to use this command, contact technical support for

assistance.

Each disk in a disk group has metadata that identifies the owning disk group, the other members of the disk

group, and the last time data was written to the disk group. The following situations cause a disk to become a

leftover:

• Disk group members’ timestamps do not match so the system designates members having an older

timestamp as leftovers.

• A disk is not detected during a rescan, then is subsequently detected.

When a disk becomes a leftover, the following changes occur:

• The disk's health becomes Degraded and its How Used state becomes LEFTOVR

• The disk is automatically excluded from the disk group, causing the disk group's health to become

Degraded or Fault, depending on the RAID level.

• The disk's fault LED becomes illuminated.

If spares are available, and the health of the disk group is Degraded, the disk group will use spares to start

reconstruction. When reconstruction is complete, you can clear the leftover disk's metadata. Clearing the

metadata will change the disk's health to OK and its How Used state to AVAIL, making the disk available for

use in a new disk group or as a spare.

If spares are not available to begin reconstruction, or reconstruction has not completed, keep the leftover

disk so that you'll have an opportunity to recover its data.

This command clears metadata from leftover disks only. If you specify disks that are not leftovers, the disks

are not changed.
