To remove a volume
# umount /dev/vx/dsk/diskgroup/volume
If the volume is listed in the /etc/fstab file, remove its entry by editing this file. Refer to your operating system documentation for more information about the format of this file and how you can modify it.
# vxvol [-g diskgroup] stop volume
# vxassist [-g diskgroup] remove volume volume
# vxedit [-g diskgroup] [-r] [-f] rm volume
The -r option to vxedit indicates recursive removal. This removes all plexes associated with the volume and all subdisks associated with those plexes. The -f option to vxedit forces removal. This is necessary if the volume is still enabled.
