create snapImage (snapGroup="
                                 snapGroupName" |
                                 snapGroups=("
                                 snapGroupName1"... "
                                 snapGroupName2"))

A snapshot image is a logical point-in-time image of the contents of an associated base virtual disk. The snapshot image is created instantly and records the state of the base virtual disk at that moment. Every snapshot image is created in the context of exactly one snapshot group. A snapshot group is a sequence of snapshot images of the associated base virtual disk. A snapshot group has one repository virtual disk used to save all of the data from the snapshot images. The snapshot images in a snapshot group have a specific order. The specific order of the snapshot images enables you to manage the snapshot images, such as restoring a specific snapshot image to the base virtual disk or deleting the snapshot images that you no longer need.

The result of creating a snapshot image of a consistency group is a snapshot image of every member virtual disk of the consistency group.
