the filer’s /etc/hosts file. Otherwise, the filer cannot send packets
to itself through the loopback address when trying to copy data.
The usable disk space of the destination volume must be greater
than or equal to the usable disk space of the source volume. Use
the df
pathname
command to see the amount of usable disk space
of a particular volume.
Each vol copy start command generates two volume copy operations: one
for reading data from the source volume and one for writing data to the des-
tination volume. Each filer supports up to four simultaneous volume copy
operations.
vol copy abort [
operation
_
number
]
terminates a volume copy operation. The
operation
_
number
parameter in
the vol copy abort command specifies which operation to terminate. If you
don’t specify an operation number, all volume copy operations are
terminated.
vol copy status [
operation
_
number
]
displays the progress of one or all volume copy operations. The operations
are numbered from 0 through 3.
vol copy throttle [
operation
_
number
]
value
controls the performance of the volume copy operation. The value ranges
from 10 (full speed) to 1 (one-tenth of full speed). You can apply the perfor-
mance value to an operation specified by the operation _ number parameter.
If you do not specify an operation number in the vol copy throttle com-
mand, the command applies to all volume copy operations. Use this
command to limit the speed of the volume copy operation if you suspect
that the volume copy operation is causing performance problems on your
filer.
The vol copy throttle command enables you to set the volume copy speed
for a volume copy operation that is in progress. To set the default volume
copy speed to be used by future volume copy operations, use the options
command to set the vol.copy.throttle option.
vol snaprestore
volname
[-s
snapshot
] [
volname
[-s
snapshot
]...] reverts a vol-
ume to a specified snapshot. If you do not specify a snapshot, the filer
prompts you for the snapshot. You can use one command to revert multiple
volumes. The volume to be reverted must be on-line and must not be a
mirror.
After the reversion, the volume is in the same state as it was when the snap-
shot was taken.
vol snapmirror on | off
enables and disables SnapMirror. If SnapMirror is enabled, you can replicate
one volume to another according to the specifications in the /etc/
snapmirror.conf file.
