Parameters

Parameter

Description

consistencyGroup

The name of the consistency group to which you want to add
a new member virtual disk. The new member virtual disk is
the base virtual disk for snapshot operations. Enclose the
consistency group name in double quotation marks (" ")
inside square brackets ([ ]).

addCGMemberVirtualDisk

The name of a base virtual disk that you want to add.
Enclose the virtual disk name in square brackets ([ ]). If the
virtual disk name has special characters, you also must
enclose the member name in double quotation marks (" ").
If the specified virtual disk is an existing repository virtual

disk or an existing snapshot virtual disk, the command fails.

repositoryVirtualDisk

This parameter performs two functions:

In an existing consistency group that has a

repository virtual disk, this parameter identifies the

repository virtual disk.

When creating a new repository virtual disk this

parameter identifies either a disk group or disk pool

in which to create the new repository virtual disk.

capacity

The size of a new repository virtual disk in either a disk
group or a disk pool. Size is defined in units of bytes, KB, MB,
GB, or TB.

Notes

You can use any combination of alphanumeric characters, underscore (_), hyphen (-), and pound (#) for the names.
Names can have a maximum of 30 characters.
A consistency group is a collection of base virtual disks that are the source virtual disks for snapshots. You collect the
base virtual disks in a consistency group so that you can perform the same snapshot operations on each of the base
virtual disks. In the context of this command, the term

member

means a base virtual disk for snapshot operations. You

can manipulate snapshot images associated with members of a consistency group through batch-style operations,
while maintaining consistency across the snapshot images.
Each member virtual disk must have a corresponding repository virtual disk. You can define the relationship between the
member virtual disk and the repository virtual disk using the repositoryVirtualDisk parameter. The
repositoryVirtualDisk parameter can perform one of these actions:

Identify an existing repository virtual disk that is connected to the consistency group.

Identify either a disk group or a disk pool in which you want to create a new repository virtual disk.

Adding a member to a consistency group with an existing repository has two purposes:

You can create an entirely new repository virtual disk by running the command without the
repositoryVirtualDisk parameter. When you run the command without the
repositoryVirtualDisk parameter, the command creates a new repository virtual disk in the disk group

or disk pool in which all the other repository volumes are stored. An example of this command usage is:
set consistencyGroup ["First_Images"] addCGMemberVirtualDisk="Data_020212"
