Note This operation is not supported for space-optimized instant snapshots.
The following command breaks the association between a snapshot hierarchy that has the snapshot volume, snapvol, at its head, and its parent volume, so that the snapshot hierarchy may be used independently of the parent volume:
vxsnap [-f] [-g diskgroup
] split snapvolume
The topmost snapshot volume in the hierarchy must have been fully synchronized for this command to succeed. Snapshots that are lower down in the hierarchy need not have been fully resynchronized.
See "Controlling instant snapshot synchronization" on page 325.
The following command splits the snapshot hierarchy under
snap2myvol from its parent volume:
vxsnap -g mydg split snap2myvol
-f(force) option must be specified.
