How to Remove and Unregister a Disk Device Group (Solstice DiskSuite/Solaris Volume Manager)

Disk device groups are Solstice DiskSuite/Solaris Volume Manager disk sets that have been registered with Sun Cluster. To remove a Solstice DiskSuite/Solaris Volume Manager disk device group, use the metaclear and metaset commands. These commands remove the disk device group with the same name and unregister the disk group as a Sun Cluster disk device group.

Refer to the Solstice DiskSuite/Solaris Volume Manager documentation for the steps to remove a disk set.
