The quarantined virtual disk’s drives are “write locked,” and the virtual disk is not
available to hosts until the virtual disk is removed from quarantine. The system
waits indefinitely for the missing drives. If the drives are found, the system
automatically removes the virtual disk from quarantine. If the drives are never found
because they have been removed or have failed, you must manually remove the
virtual disk from quarantine.
If the missing drives cannot be restored (for example, a failed drive), you can
remove the virtual disk from quarantine to restore operation in some cases. If you
remove from quarantine a virtual disk that is not missing too many drives, its status
changes to critical. Then, if spares of the appropriate size are available,
reconstruction begins.
Note – After you remove the virtual disk from quarantine, make sure that a spare
drive is available to let the virtual disk reconstruct.
Caution – If the virtual disk does not have enough drives to continue operation,
when the virtual disk is removed from quarantine it goes offline and its data cannot
be recovered.
To remove a virtual disk from quarantine:
1. Select Manage > Utilities > Recovery Utilities > Vdisk Quarantine.
For each virtual disk, the virtual disk panel shows a status icon; the name, RAID
level, size, number of disk drives, and number of volumes; and utility status, if any.
2. Select the virtual disk to remove from quarantine.
3. Click Dequarantine Selected Virtual Disk.
Verifying a Virtual Disk
When you suspect that a redundant virtual disk has a problem, you can verify its
data. For example, if the system was operating outside the normal temperature range
for any length of time. The RAID level determines the Verify utility's behavior:
■ For RAID 3, 5, 6, and 50, the Verify utility verifies all parity blocks in the virtual
disk.
■ For RAID 1 and 10, the Verify utility compares the primary and secondary
drives.
