create task
Description
Creates a task that can be scheduled. You can create a task to take a snapshot of a master volume,
to copy a snapshot or a master volume to a new standard volume, or to reset a snapshot.
CAUTION:
Before scheduling a reset snapshot task, consider that if the snapshot is mounted to a
host operating system, the snapshot must be unmounted before the reset is performed; leaving it
mounted can cause data corruption. You should create a scheduled job on the host to unmount the
snapshot prior to resetting the snapshot.
Syntax
To create a task to take a snapshot:

Parameters
type TakeSnapshot|ResetSnapshot|VolumeCopy
The task type:
•
TakeSnapshot
: Takes a snapshot of a master volume.
•
ResetSnapshot
: Deletes the data in the snapshot and resets it to the current data in the
associated master volume. The snapshot's name and other volume characteristics are not
changed.
CAUTION:
Before scheduling a reset snapshot task, consider that if the snapshot is mounted to a
host operating system, the snapshot must be unmounted before the reset is performed; leaving it
mounted can cause data corruption.
•
VolumeCopy
: Copies a snapshot or a master volume to a new standard volume. The command
creates the destination volume you specify, which must be in a vdisk owned by the same
controller as the source volume.
