4 Virtual port groups
Some virtualized storage arrays limit the number of LUNs exposed to a host to 256. To access
more than 256 LUNs per target, each MPX200 blade supports up to four VPGs. If you want your
iSCSI hosts to have access to more than 256 distinct LUNS from a specified Fibre Channel target
array, you must enable and configure additional VPGs.
Each blade has VPG 1 enabled by default; VPG 1 is the primary virtual port group and cannot
be disabled. Enabling extra virtual port groups creates additional logical Fibre Channel adapter
initiator ports on the fabric. These ports act as separate Fibre Channel adapter host ports, and an
additional 256 LUNs can be presented to each of them. With all four virtual port groups enabled,
a single MPX200 blade can access up to 1,024 LUNs from a single Fibre Channel storage array.
Displaying virtual port groups
Use the show vpgroups command to display virtual port group information. For example:
MPX200 <1> (admin) #> show vpgroups

The following wizard will query for attributes before persisting

press 'q' or 'Q' and the ENTER key to do so.
