# 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 244.
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 239.
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]
This command shows the percentage progress of the synchronization of a snapshot
or volume. If no volume is specified, information about the snapshots for all the
volumes in a disk group is displayed. The following example shows a volume,
