Dell PowerVault ME5 Series Storage System CLI Reference Guide

You can create a task to:

• Enable drive spin down for spinning disks. The disks cannot be in a virtual pool. The disks cannot be using ADAPT data protection. You can use this to enable or resume spin down during hours of infrequent activity. When drive spin down is enabled, disks will spin down after 60 minutes of inactivity by default.
• Disable drive spin down. You can use this to disable or suspend spin down during hours of frequent activity.
• Create a snapshot of a source volume, which can be a virtual base volume or a virtual snapshot.
• Reset a snapshot. This deletes the data in the snapshot and resets it to the current data in the volume from which the snapshot was created. The snapshot name and other volume characteristics are not changed.
• Replicate a virtual replication set primary volume or volume group to a peer system

Optional. For a Replicate task this specifies to replicate the most recent snapshot of the primary volume in a single-volume replication set. At the time the scheduled replication occurs, the snapshot must exist. This snapshot may have been created either manually or by scheduling the snapshot. This option cannot be used for a replication set that contains a volume group.

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

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.

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.

For a ResetSnapshot task this specifies the name or serial number of the snapshot to reset. A name that includes a space must be enclosed in double quotes.

For a TakeSnapshot task this specifies the name or serial number of the source volume of which to take a snapshot. A name that includes a space must be enclosed in double quotes.

The task type:

• TakeSnapshot: Creates a snapshot.
• ResetSnapshot: Resets the data in a snapshot.
• Replicate: Replicates a virtual replication set primary volume or volume group to a peer system.
• EnableDSD: Enables drive spin down.
• DisableDSD: Disables drive spin down.
• name

A name for the new task. 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.
