The following command removes disks disk07 and disk08 from rootdg to

form a new disk group, dg1:

# vxdg -o expand split rootdg dg1 disk07 disk08

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, dg1:

# vxprint

Disk group: rootdg
