    Associated objects

    Snapshot image

    You can view the snapshot images associated with the snapshot volume. A snapshot image is a logical copy of volume data, captured at a particular point-in-time. Like a restore point, snapshot images allow you to roll back to a known good data set. Although the host can access the snapshot image, it cannot directly read or write to it.

    Base volume

    You can view the base volume associated with the snapshot volume. A base volume is the source from which a snapshot image is created. It can be a thick or thin volume and is typically assigned to a host. The base volume can reside in either a volume group or disk pool.

    Snapshot group

    You can view the snapshot group associated with the snapshot volume. A snapshot group is a collection of snapshot images from a single base volume.
