HP P2000 G3 MSA System CLI Reference Guide 57
To create a task to disable spin-down for all disks:
create task type DisableDSD taskDSDsuspend
Parameters type TakeSnapshot|ResetSnapshot|VolumeCopy|ReplicateVolume|EnableDSD
|DisableDSD
The task type:
• TakeSnapshot: Takes a snapshot of a standard or 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.
• VolumeCopy: Copies a standard, master, or snapshot 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.
• ReplicateVolume: Replicates a replication set's primary volume to a remote system.
• EnableDSD: Enables spin-down for all vdisks. You can use this to enable or resume disk
spin-down during hours of infrequent activity.
• DisableDSD: Disables spin-down for all vdisks. You can use this to disable or suspend disk
spin-down during hours of frequent activity.
source-volume volume
For a TakeSnapshot task, the name or serial number of the standard or master volume to take a
snapshot of. For a VolumeCopy task, the name or serial number of the standard, master, or
snapshot volume to copy. For a ReplicateVolume task, the name or serial number of the primary
volume to replicate. For volume syntax, see Command syntax on page 21.
snapshot-prefix prefix
A label to identify snapshots created by this task. Snapshot names have the format prefix_s#,
where # starts at 001.
retention-count #
For a TakeSnapshot task this parameter specifies the number of snapshots created by this task to
retain, from 1 to the licensed limit. When a new snapshot exceeds this limit, the oldest snapshot with
the same prefix is deleted.
For a ReplicateVolume task this parameter specifies the number of replication images created by
this task to retain, from 2 to 32. When a new image exceeds this limit, the oldest image with the
same prefix is deleted. This parameter applies to the primary volume only; for the secondary volume,
images will accumulate until either the secondary vdisk's space limit is reached or the maximum
number of images is reached, after which the oldest image will be deleted as new images are
created.
snapshot-volume volume
Name or serial number of the snapshot to reset. For volume syntax, see Command syntax on
page 21.
dest-vdisk vdisk
Name or serial number of the destination vdisk for the volume copy. For vdisk syntax, see Command
syntax on page 21.
dest-prefix prefix
A label to identify the volume copy created by this task. Copy names have the format prefix_c#,
where # starts at 001.
