trust
Description
Enables an offline virtual disk to be brought online for emergency data collection
only. It 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 re-synchronizes the time and date stamp and any other
metadata on a bad disk drive. This makes the disk drive an active member of the
virtual disk again. You might need to do this when:
Q
One or more disks of a virtual disk start up more slowly or were powered on after
the rest of the disks in the virtual disk. This causes the date and time stamps to
differ, which the system interprets as a problem with the “late” disks. In this case,
the virtual disk functions normally after being trusted.
Q
A virtual disk is offline because a drive is failing, you have no data backup, and
you want to try to recover the data from the virtual disk. In this case, trust may
work, but only as long as the failing drive continues to operate.
When the “trusted” virtual disk is back online, back up its data and audit the data to
make sure that it is intact. Then delete that virtual disk, create a new virtual disk,
and restore data from the backup to the new virtual disk. Using a trusted virtual disk
is only a disaster-recovery measure; the virtual disk has no tolerance for any
additional failures.
Input
To enable the trust command:
To trust a virtual disk:

trust vdisk
vdisk
