If the missing disks cannot be restored (for example, they failed), you can dequarantine the vdisk to
restore operation in some cases. If you dequarantine a vdisk that is not missing too many disks, its
status changes to CRIT. Then, if spares of the appropriate size are available, reconstruction begins.
If a replacement disk (reconstruct target) is missing on power up, the vdisk becomes quarantined;
when the disk is found, the vdisk is dequarantined and reconstruction starts. If reconstruction was in
process, it continues where it left off.
NOTE: The only commands allowed for a quarantined vdisk are dequarantine and delete
vdisk. If you delete a quarantined vdisk and its missing disks later come online, the vdisk will
reappear as quarantined or offline and you must delete it again (to clear those disks).
CAUTION:
removed from quarantine its status changes to OFFL and its data cannot be recovered. To continue
operation, a RAID-3 or RAID-5 vdisk can be missing one disk; a RAID-6 vdisk can be missing one or
two disks; a RAID- 1 0 or RAID-50 vdisk can be missing one disk per sub-vdisk. For example, a 16-disk
RAID- 1 0 vdisk can remain online (critical) with 8 disks missing if one disk per mirror is missing.
Syntax
dequarantine vdisk vdisk
Parameters vdisk vdisk
Name or serial number of the vdisk to remove from quarantine. For vdisk syntax, see
syntax on page 21.
Example After determining that vdisk VD1 is quarantined, remove it from quarantine and re-check its status:
# show vdisks
Name ... Stat ...
-----------------
VD1 ... QTDN ... (Quarantined with down disks)
-----------------
# dequarantine vdisk VD1
Success: Command completed successfully
# show vdisks
Name ... Stat ...
-----------------
VD1 ... FTDN ... (Fault tolerant, down)
