Removing a snapshot volume

If a snapshot volume is no longer needed, you can remove it and free up the disk

space for other uses by using the vxedit rm command.

■ You must be logged in as root.

■ If the volume is on a mounted file system, you must unmount it

before removing the volume.

Prerequisites

To remove a snapplan and snapshot volume

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 -f unprepare volume

Remove the snapplan:

# /opt/VRTS/bin/dbed_vmchecksnap -S db -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
