193Creating and administering disk groups
Reorganizing the contents of disk groups
Moving objects between disk groups
To move a self-contained set of VxVM objects from an imported source disk group to an
imported target disk group, use the following command:
# vxdg [-o expand] [-o override|verify] move sourcedg targetdg \
object ...
The -o expand option ensures that the objects that are actually moved include all other
disks containing subdisks that are associated with the specified objects or with objects that
they contain.
The default behavior of
vxdg when moving licensed disks in an EMC array is to perform
an EMC disk compatibility check for each disk involved in the move. If the compatibility
checks succeed, the move takes place.
vxdg then checks again to ensure that the
configuration has not changed since it performed the compatibility check. If the
configuration has changed,
vxdg attempts to perform the entire move again.
The
-o override option enables the move to take place without any EMC checking.
The
-o verify option returns the access names of the disks that would be moved but does
not perform the move.
Note: The -o override and -o verify options require a valid EMC license.
See “Moving objects between disk groups” on page 417 for information on how to move
objects between disk groups in a cluster.
For example, the following output from
vxprint shows the contents of disk groups
rootdg and mydg:
# vxprint
