1. remove any volumes from the disks
vxassist –g disk-group remove volume volume-name
b. repeat the above procedure for each volume on the disk
2. remove disks from the disk group
vxdg –g disk-group rmdisk vxvm-disk-name
b. repeat the above procedure until there is one disk remaining in the disk group; you cannot remove the last disk from a disk group. At this point you will just need to remove the disk group itself.
3. remove the disk group
vxdg destroy disk-group
