Changes parameters for a TakeSnapshot . For these types of tasks, you can change parameters other than name, type, or associated volumes. If you change the parameters for a running task, the changes will take effect the next time the task runs.

If you want to change parameters for a ResetSnapshot task or the name, type, or associated volumes for another type of task, create a new task to replace the existing one.

set task

[last-snapshot enabled|disabled|on|off]

[replication-set <replication-set-ID>]

[retention-count <#>]

[snapshot-prefix <prefix>]

< name>

Optional. For a Replicate task this specifies to replicate the most recent snapshot of the primary volume. At the time the scheduled replication occurs, the snapshot must exist. This snapshot may have been created either manually or by a host-initiated snapshot creation. If last-snapshot is specified and no snapshot exists for the volume when the scheduled replication begins, the system generates an error and the replication fails.

Optional. For a Replicate task this specifies the ID of the replication set to replicate.

Optional. For a TakeSnapshot task this specifies the number of snapshots created by this task to retain, from 1 to 16. When a new snapshot exceeds this limit, the oldest snapshot is reset and renamed with the same prefix. The oldest snapshot is the one whose name has the lowest number (such as 01 as compared with 02). Resetting the oldest snapshot does not change its creation date/time. If you reduce the retention count for a task, excess snapshots will be removed the next time the task runs.

Optional. For a TakeSnapshot task this specifies a label to identify snapshots created by this task. Input rules:

• The value is case sensitive.
• The value can have a maximum of 26 bytes.
• The value can include spaces and printable UTF-8 characters except: " , < \
• A value that includes a space must be enclosed in double quotes.

The name of the task to change. Input rules:

• The value is case sensitive.
• The value can have a maximum of 32 bytes.
• The value can include spaces and printable UTF-8 characters except: " , < \
• A value that includes a space must be enclosed in double quotes.
