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 disks. You can use this to enable or resume spin down during hours of infrequent activity. • DisableDSD: Disables spin down for all disks. You can use this to disable or suspend 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 of which to take a snapshot. 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" (page 20). snapshot-prefix prefix A label to identify snapshots created by this task. The prefix is case sensitive; cannot include a comma, double quote, left angle bracket, or backslash; and can have a maximum of 26 bytes. 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 The name or serial number of the snapshot to reset. For volume syntax, see "Command syntax" (page 20). dest-vdisk vdisk Name or serial number of the destination vdisk for the volume copy. For vdisk syntax, see "Command syntax" (page 20). dest-prefix prefix A label to identify the volume copy created by this task. The prefix is case sensitive; cannot include a comma, double quote, left angle bracket, or backslash; and can have a maximum of 26 bytes. Copy names have the format prefix_c#, where # starts at 001. modified-snapshot yes|no Optional. Specifies whether to include or exclude modified write data from the snapshot in the copy. This parameter applies only when the source volume is a snapshot; it is ignored if the source volume is a master volume. • yes: Include modified snapshot data. • no: Exclude modified snapshot data. If this parameter is omitted for a snapshot, modified snapshot data is excluded. 60 Alphabetical list of commands
