Enabling Virtual Port Groups
Each iSR6250 router blade has one virtual port group (VPG) enabled by default,
which gives the iSCSI hosts access to 256 LUNs. You can enable and configure
additional VPGs to give the iSCSI hosts access to more than 256 distinct LUNS
from a given FC Target Array.
Each blade has VPG 1 enabled by default; VPG 1 is the primary virtual port group
and cannot be disabled. Enabling additional virtual port groups creates additional
logical FC HBA initiator ports on the fabric. These ports act as separate FC HBA
host ports, and additional 256 LUNs can be presented to each of them. With all
four VPGs enabled, a single iSR6250 blade can access up to1024 LUNs from a
single target WWPN.
You can display virtual port group information using the show vpgroups
command in the CLI, as shown in the following example.
iSR6200 <1> (admin) #> show vpgroups
