The following command breaks the association between a full-sized instant snapshot volume, snapvol, and its parent volume, so that the snapshot may be used as an independent volume:
# vxsnap [-f] [-g
diskgroup] dis
snapvolume|
snapvolume_set
This operation fails if the snapshot, snapvol, has a snapshot hierarchy below it that contains unsynchronized snapshots. If this happens, the dependent snapshots must be fully synchronized from snapvol. When no dependent snapshots remain, snapvol may be dissociated. The snapshot hierarchy is then adopted by snapvol's parent volume.
Note To be usable after dissociation, the snapshot volume and any snapshots in the hierarchy must have been fully synchronized. See Controlling instant snapshot synchronization for more information. In addition, you cannot dissociate a snapshot if synchronization of any of the dependent snapshots in the hierarchy is incomplete. If an incomplete snapshot is dissociated, it is unusable and should be deleted as described in Removing an instant snapshot.
The following command dissociates the snapshot, snap2myvol
, from its parent volume:
# vxsnap -g mydg dis snap2myvol
Note
When applied to a volume set or to a component volume of a volume set, this operation can result in inconsistencies in the snapshot hierarchy in the case of a system crash or hardware failure. If the operation is applied to a volume set, the -f
(force) option must be specified.
