Removing an instant snapshot
When you have dissociated a full-sized instant snapshot, you can use the vxedit
command to delete it altogether, as shown in this example:
# vxedit -g mydg -r rm snap2myvol
You can also use this command to remove a space-optimized instant snapshot
from its cache.
See “Removing a cache” on page 395.
Splitting an instant snapshot hierarchy
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 391.
The following command splits the snapshot hierarchy under snap2myvol from
its parent volume:
# vxsnap -g mydg split snap2myvol
Warning: 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.
Displaying instant snapshot information
The vxsnap print command may be used to display information about the
snapshots that are associated with a volume.
# vxsnap [-g diskgroup] print [vol]
