clear disk-metadata Description Clears metadata from leftover disks. CAUTION: • Only use this command when all vdisks are online and leftover disks exist. Improper use of this command may result in data loss. • Do not use this command when a vdisk is offline and one or more leftover disks exist. If you are uncertain whether to use this command, contact technical support for further assistance. Each disk in a vdisk has metadata that identifies the owning vdisk, the other members of the vdisk, and the last time data was written to the vdisk. The following situations cause a disk to become a leftover: • Vdisk 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 vdisk, causing the vdisk's health to become Degraded or Fault, depending on the RAID level. • The disk's Fault/UID LED is illuminated amber. • For a 2U12 or 2U24 enclosure, the disk's fault LED becomes illuminated. If spares are available, and the health of the vdisk is Degraded, the vdisk will use them 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 vdisk 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. Syntax clear disk-metadata disks Parameters disks IDs of the leftover disks to clear metadata from. For disk syntax, see "Command syntax" (page 20). Example Show disk usage: # show disks Location ... How Used ... 1.1 ... LEFTOVR ... 1.2 ... VDISK ... ... Clear metadata from a leftover disk: # clear disk-metadata 1.1 Info: Updating disk list... Info: Disk disk_1.1 metadata was cleared. (2012-01-18 10:35:39) Success: Command completed successfully. - Metadata was cleared. (2012-01-18 10:35:39) clear disk-metadata 37

clear disk-metadata

Description

Clears metadata from leftover disks.

CAUTION:

•

Only use this command when all vdisks are online and leftover disks exist. Improper use of this

command may result in data loss.

•

Do not use this command when a vdisk is offline and one or more leftover disks exist.

If you are uncertain whether to use this command, contact technical support for further assistance.

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

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

leftover

•

Vdisk 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 vdisk, causing the vdisk's health to become

Degraded

Fault

, depending on the RAID level.

•

The disk's Fault/UID LED is illuminated amber.

•

For a 2U12 or 2U24 enclosure, the disk's fault LED becomes illuminated.

If spares are available, and the health of the vdisk is

Degraded

, the vdisk will use them 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

and its How Used state to

AVAIL

, making the disk

available for use in a new vdisk 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.
