VERITAS Volume Manager 4.1 Administrator's Guide

Creating and Administering Disk Groups
Chapter 4188
Disabling a Disk Group
To disable a disk group, unmount and stop any volumes in the disk
group, and then use the following command to deport it:
# vxdg deport diskgroup
Deporting a disk group does not actually remove the disk group. It
disables use of the disk group by the system. Disks in a deported disk
group can be reused, reinitialized, added to other disk groups, or
imported for use on other systems. Use the vxdg import command to
re-enable access to the disk group.
