dequarantine Description A previously fault-tolerant vdisk becomes quarantined when not all of its disks are detected after a restart or power cycle. Quarantine isolates the vdisk from host access, and prevents the storage system from making the vdisk critical and starting reconstruction when disks are "missing" for these reasons: • Slow to spin up after system power-up • Not properly seated in their slots • In an powered-off enclosure • Inserted from a different system and contains old metadata The vdisk can be fully recovered if the missing disks can be restored. Make sure that no disks have been inadvertently removed and that no cables have been unplugged. Sometimes not all disks in the vdisk power up. Check that all enclosures have restarted after a power failure. If these problems are found and then fixed, the vdisk recovers and no data is lost. The quarantined vdisk's disks are "write locked" and the vdisk is not available to hosts until the vdisk is removed from quarantine. The system waits indefinitely for the missing disks. If the disks are found, the system automatically removes the vdisk from quarantine. If the disks are never found because they have been removed or have failed, you must manually remove the vdisk from quarantine. If the missing disks cannot be restored (for example, they failed), you can remove the vdisk from quarantine to restore operation in some cases. If you remove from quarantine a vdisk that is not missing too many disks, its status changes to critical. Then, if spares of the appropriate size are available, reconstruction begins. NOTE: After you remove the vdisk from quarantine, make sure that a spare disk is available to let the vdisk reconstruct. CAUTION: If the vdisk does not have enough disks to continue operation, when the vdisk is removed from quarantine it goes offline and its data cannot be recovered. Syntax dequarantine vdisk vdisk Parameters vdisk vdisk Name or serial number of the vdisk to remove from quarantine. For syntax, see Command syntax. Example After determining that vdisk VD1 is quarantined, remove it from quarantine and re-check its status: # show vdisks Name ... Stat VD1 ... QTDN ...

dequarantine
Description
A previously fault-tolerant vdisk becomes quarantined when not all of its disks are detected after a
restart or power cycle. Quarantine isolates the vdisk from host access, and prevents the storage
system from making the vdisk critical and starting reconstruction when disks are “missing” for these
reasons:
•
Slow to spin up after system power-up
•
Not properly seated in their slots
•
In an powered-off enclosure
•
Inserted from a different system and contains old metadata
The vdisk can be fully recovered if the missing disks can be restored. Make sure that no disks have
been inadvertently removed and that no cables have been unplugged. Sometimes not all disks in the
vdisk power up. Check that all enclosures have restarted after a power failure. If these problems are
found and then fixed, the vdisk recovers and no data is lost.
The quarantined vdisk's disks are “write locked” and the vdisk is not available to hosts until the vdisk
is removed from quarantine. The system waits indefinitely for the missing disks. If the disks are found,
the system automatically removes the vdisk from quarantine. If the disks are never found because
they have been removed or have failed, you must manually remove the vdisk from quarantine.
If the missing disks cannot be restored (for example, they failed), you can remove the vdisk from
quarantine to restore operation in some cases. If you remove from quarantine a vdisk that is not
missing too many disks, its status changes to critical. Then, if spares of the appropriate size are
available, reconstruction begins.
NOTE:
After you remove the vdisk from quarantine, make sure that a spare disk is available to let
the vdisk reconstruct.
CAUTION:
If the vdisk does not have enough disks to continue operation, when the vdisk is
removed from quarantine it goes offline and its data cannot be recovered.
