Veritas Volume Manager 5.1 SP1 Administrator"s Guide (5900-1506, April 2011)

Identifier (AVID) as an index in the DMP metanode name. The DMP metanode
name is in the format enclosureID_AVID.
The VxVM utilities such as vxdisk list display the DMP metanode name, which
includes the AVID property. Use the AVID to correlate the DMP metanode name
to the LUN displayed in the array management interface (GUI or CLI) .
If the ASL does not provide the array volume ID property, then DMP generates
an index number. DMP sorts the devices seen from an array by the LUN serial
number and then assigns the index number. In this case, the DMP metanode name
is in the format enclosureID_index.
In a cluster environment, the DMP device names are the same across all nodes in
the cluster.
For example, on an EMC CX array where the enclosure is emc_clariion0 and the
array volume ID provided by the ASL is 91, the DMP metanode name is
emc_clariion0_91. The following sample output shows the DMP metanode names:
$ vxdisk list
emc_clariion0_91 auto:cdsdisk emc_clariion0_91 dg1 online shared
emc_clariion0_92 auto:cdsdisk emc_clariion0_92 dg1 online shared
emc_clariion0_93 auto:cdsdisk emc_clariion0_93 dg1 online shared
emc_clariion0_282 auto:cdsdisk emc_clariion0_282 dg1 online shared
emc_clariion0_283 auto:cdsdisk emc_clariion0_283 dg1 online shared
emc_clariion0_284 auto:cdsdisk emc_clariion0_284 dg1 online shared
Discovering the association between enclosure-based
disk names and OS-based disk names
If you enable enclosure-based naming, the vxprint command displays the structure
of a volume using enclosure-based disk device names (disk access names) rather
than OS-based names.
