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:
# vxprint
Disk group: rootdg
