SSSU Command Reference
40 Command View EVA Storage System Scripting Utility Reference Guide
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.
