dm disk07 c1t99d0 - 17678493 - - - -

dm disk08 c1t100d0 - 17678493 - - - -

The following commands would also achieve the same result:

# vxdg move dg1 rootdg disk01 disk05

# vxdg move dg1 rootdg vol1

Splitting Disk Groups

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 ...

For a description of the -o expand, -o override, and -o verify options, see

“Moving Objects Between Disk Groups” on page 181.

See “Splitting Disk Groups” on page 376 for more information on

splitting shared disk groups in clusters.

For example, the following output from vxprint shows the contents of

disk group rootdg:

# vxprint

Disk group: rootdg
