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|
snapvolume_set
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 349.
The following command splits the snapshot hierarchy under snap2myvol
from its parent volume:
# vxsnap -g mydg split snap2myvol
-f
(force) option must be specified.
