SSSU Command Reference

ADD SNAPSHOT

The ADD SNAPSHOT command creates a picture (not a full copy) of a virtual disk family’s active virtual disk.

Note: Creating snapshots of virtual disks depends on your licensing level. Attempting to add a snapshot without the license returns an error message. This message indicates that you need to enter your licensing information in the Command View EVA. You must have a registered license.

Syntax

ADD SNAPSHOT <snapshot_name> VDISK=<vdisk_to_snapshot>

Switches

The following switches are available with the ADD SNAPSHOT command.

ALLOCATION_POLICY=

Indicates how the space for the snapshot is allocated.

■DEMAND—Storage is allocated for the snapshot only when required. As the snapshot and the original storage’s information diverges, the space allocated for the snapshot increases.

■FULLY—All storage required to fully contain a snapshot is allocated when the snapshot is created. This is the conservative method to create a snapshot, because adequate space is guaranteed for a full snapshot. This is the default.

OS_UNIT_ID=

The ID that is presented to the host operating system. If set to zero, no ID is presented to the host.

REDUNDANCY=

The amount of data protection set when creating the virtual disk. If not specified, the default is Vraid0.
