Trust - HP P2000 Reference Manual

trust

Description Enables an offline vdisk to be brought online for emergency data recovery. This command must be
enabled before each use.
CAUTION:
intended for disaster recovery only.
CAUTION:
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.
