trust

Description Enables an offline vdisk to be brought online for emergency data collection. 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.

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

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

• One or more disks in a vdisk start up more slowly or were powered on after the rest of the disks

in the vdisk. This causes the date and time stamps to differ, which the system interprets as a

problem with the "late" disks. In this case, the vdisk functions normally after being trusted.

• 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.

Virtual-disk VD1 has been trusted.
