Chapter 5228
Removing a Disk Group
To remove a disk group, unmount and stop any volumes in the disk
group, and then use the following command:
# vxdg deport diskgroup
Deporting a disk group does not actually remove the disk group. It
disables use of the disk group by the system. However, disks that are in a
deported disk group can be reused, reinitialized, or added to other disk
groups, or imported to use on other systems.
