trust Description Enables an offline vdisk to be brought online for emergency data recovery. This command must be enabled before each use. CAUTION: This command can cause unstable operation and data loss if used improperly. It is intended for disaster recovery only. CAUTION: Do not use this command on a vdisk having critical status. Instead, add a spare and let the system reconstruct the vdisk. The trust command resynchronizes the time and date stamp and any other metadata on a bad disk. This makes the disk an active member of the vdisk again. You might need to do this when a vdisk is offline because a disk is failing, you have no data backup, and you want to try to recover the data from the vdisk. In this case, trust may work, but only as long as the failing disk continues to operate. When the "trusted" vdisk is back online, back up its data and audit the data to make sure that it is intact. Then delete that vdisk, create a new vdisk, and restore data from the backup to the new vdisk. Using a trusted vdisk is only a disaster-recovery measure; the vdisk has no tolerance for any additional failures. Syntax To enable the trust command: trust enable To trust a vdisk: trust vdisk vdisk Parameters enable Enables the trust command before use. vdisk vdisk Name or serial number of the vdisk to trust. For vdisk syntax, see Command syntax on page 21.

Alphabetical list of commands

trust

Description

Enables an offline vdisk to be brought online for emergency data recovery. This command must be

enabled before each use.

CAUTION:

This command can cause unstable operation and data loss if used improperly. It is

intended for disaster recovery only.

CAUTION:

Do not use this command on a vdisk having critical status. Instead, add a spare and let

the system reconstruct the vdisk.

The trust command resynchronizes the time and date stamp and any other metadata on a bad disk.

This makes the disk an active member of the vdisk again. You might need to do this when a vdisk is

offline because a disk is failing, you have no data backup, and you want to try to recover the data

from the vdisk. In this case, trust may work, but only as long as the failing disk continues to operate.

When the “trusted” vdisk is back online, back up its data and audit the data to make sure that it is

intact. Then delete that vdisk, create a new vdisk, and restore data from the backup to the new vdisk.

Using a trusted vdisk is only a disaster-recovery measure; the vdisk has no tolerance for any

additional failures.

Syntax

To enable the

trust

command:

trust enable

To trust a vdisk:

trust vdisk

vdisk

Parameters

enable

Enables the trust command before use.

vdisk

Name or serial number of the vdisk to trust. For vdisk syntax, see

Command syntax

on page 21.

Example

Enable the trust command and then trust vdisk

VD1

# trust enable

Success: Command completed successfully.

# trust vdisk VD1

Success: Command completed successfully.
