fc srp initiator-wwpn
To manually create, on a physical FC gateway port, a virtual port that points to an initiator, enter the
fc srp initiator-wwpn
command in Global Configuration mode.
fc srp initiator-wwpn
guid extension slot#
/
port# wwpn
Syntax Description

Configure WWPNs for initiators so that FC devices can recognize them and communicate with them.
With virtual ports (NL_ports), physical FC ports can point to multiple initiators, and multiple ports can
point to the same initiator. For instance, if you have Initiators X and Y and Physical FC Ports A and B,
you can create the following virtual ports:
• virtual port AX on port A that points to initiator X
• virtual port AY on port A that points to initiator Y
• virtual port BX on port B that points to initiator X
• virtual port BY on port B that points to initiator Y
As you can see, in this way, multiple virtual ports can point to one initiator and individual physical ports
can support multiple initiators.
When you enter a question mark (?) after the port# variable, the CLI provides a suggested WWPN value.
Note Use the recommended WWPN unless you have a compelling reason to do otherwise. We strongly
recommend that you use the
fc srp initiator
command with the
auto-bind
keyword to create initiator
entries and assign WWPNs to initiators.
guid Global unique identifier (GUID) of the SRP host (initiator) that you want to
connect to a Fibre Channel SAN.
extension GUID extension of the SRP host that you want to connect to a Fibre Channel
SAN.
slot# Slot of the FC gateway expansion module that you want to use.
port# Fibre Channel gateway port that you want to use to connect your initiator to
the SAN.
wwpn WWPN to assign to the new virtual port.
