volume group

On AIX systems, physical disk volumes are organized into volume groups. The partition size of a physical volume is determined by the volume group that it belongs to. If multiple physical volumes belong to the same volume group, then they must all have the same partition size. A typical partition size might be 16 or 32 megabytes.

major number of <volume group> : integer

Returns the major number of the specified volume group. Each logical volume is represented by a device special file (located in directory /etc). The major number of the device special file is associated with the volume group containing the logical volume, and the minor number of the device special file is associated with the logical volume.Example: major number of volume group "dave" of logical volume manager - Returns the major number of the specified volume group.
