To remove a self-contained set of VxVM objects from an imported source disk group to a new target disk group, use the following command:
# vxdg [-o expand] [-o override|verify] split sourcedg targetdg \ object ...
The following output from vxprint shows the contents of disk group rootdg.
The output includes two utility fields, TUTIL0 and PUTIL0.. VxVM creates these fields to manage objects and communications between different commands and Symantec products. The TUTIL0 values are temporary; they are not maintained on reboot. The PUTIL0 values are persistent; they are maintained on reboot.

The following command removes disks rootdg07 and rootdg08 from rootdg to form a new disk group, mydg:
# vxdg -o expand split rootdg mydg rootdg07 rootdg08
The moved volumes are initially disabled following the split. Use the following commands to recover and restart the volumes in the new target disk group:
# vxrecover -g targetdg -m [volume ...] # vxvol -g targetdg startall
The output from vxprint after the split shows the new disk group, mydg:
