To remove the snapshot and free up the storage used by it:
-
If the snapshot has been taken, remove the snapshot as follows:
# vxsnap -g diskgroup dis snapshot_volume
# vxvol -g diskgroup stop snapshot_volume
# vxedit -g diskgroup -rf rm snapshot_volume
-
If the snapshot has not been taken and the snapshot plex (mirror) exists, remove the snapshot as follows:
# vxsnap -g diskgroup rmmir volume
-
Remove the DCO and DCO volume:
# vxsnap -g diskgroup unprepare volume
-
Remove the snapplan.
# /opt/VRTS/bin/dbed_vmchecksnap -S PROD -f snapplan -o remove
For example, the following commands will remove a snapshot volume from disk group PRODdg:
# vxsnap -g PRODdg dis snap_v1
# vxvol -g PRODdg stop snap_v1
# vxedit -g PRODdg -rf rm snap_v1
