Reorganizing the Contents of Disk Groups

128 VERITAS Volume Manager Administrator’s Guide

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 subdisksthat are associated withthe speciﬁed objectsor with objectsthat

they contain.

The default behavior of vxdg when moving licensed disks in an EMC array is to perform

a 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 DiskGroups” onpage 265 for informationon 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 dg1:

# vxprint
