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 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 the parent volume of snapvol.

The following command dissociates the snapshot, snap2myvol, from its parent volume:

# vxsnap -g mydg dis snap2myvol
