The vxdg utility performs administrative operations on Veritas Volume Manager (VxVM) disk groups. There are two types of disk groups, private and shared. For information about the differences between private and shared disk groups, see:

About private and shared disk groups

The vxdg import operation makes the specified disk group available on the local system. Any data stored on the disk group is accessible, including all configuration information such as disk and volume configurations. The vxdg deport operation disables access to the specified disk group. A disk group cannot be deported if any volumes in the disk group are currently open.

The following links provide information on using the vxdg utility for importing and deporting disk groups, clearing import locks, creating shared disk groups, and displaying free space in disk groups:

vxdg (1M) 6.0.1 manual pages:

vxdg (1M) manual pages for other releases can be found on the SORT website.

Diskgroup types can be confusing if you use Windows and UNIX as in particular if you use the "-s" flag of "vxdg import" command in UNIX, then this imports diskgroup as shared, meaning it can be simultaneously imported on several nodes so that volumes in the disk group can be written to simultaneously from different nodes.  However if you use the "-s"  flag of "vxdg import" command in Windows, then this makes the diskgroup a "Cluster dynamic disk group" meaning you can use it in a cluster to fail between nodes, but NOT use simultaneously and many people would refered to this "shared" between the 2 nodes and so may call it a "shared diskgroup"
