Creating A Consistency Group Snapshot Image

To create a new snapshot image for each base virtual disk in snapshot consistency group, use the create cgSnapImage command. The command will suspend all pending I/O operations to each base virtual disk that is a member of the consistency group before creating the snapshot images. If the snapshot image cannot be completed successfully for all of the consistency group members, this command fails and new snapshot images are not created.

Since all members of a snapshot consistency group normally contain the same number of snapshot images, adding a new member to a snapshot consistency group with this command create a new member lacking previously created snapshot images. This is not an indication of an error condition.

To create a consistency group snapshot image: 
create cgSnapImage consistencyGroup="
                                    consistencyGroupName"
where, consistencyGroup is the name of the consistency group for which you are creating snapshot images.
