Considerations for initiator and target ports
The following connections are possible for the Fibre Channel Protocol (FCP) initiator (host) and
target ports through AG:
•
All F_Ports connect to all initiator ports.
•
All F_Ports connect to all target ports.
•
Some F_Ports connect to initiator ports and some F_Ports connect to target ports.
For the last case, communication between initiator and target ports is not supported if both are
mapped to the same N_Port. Therefore, follow these recommendations for initiator and target port
mapping:
•
If connecting a host and target port to the same AG, you should map them to separate N_Ports
and connect those N_Ports to the same fabric.
•
Use separate port groups for initiator and target ports.
•
When configuring secondary port mapping for failover and failback situations, make sure that
initiator and target F_Ports will not fail over or fail back to the same N_Port.
Brocade 8000 mapping differences
The Brocade 8000 contains 24 internal FCoE ports and 8 external Fibre Channel ports. In Access
Gateway mode, the internal FCoE ports are configured logically as F_Ports, while the external Fibre
Channel ports are configured as N_Ports. The FCoE ports are divided into six groups, or trunks,
consisting of four ports each. All four ports in a group are mapped to one N_Port. Although you can
change the default port mapping for these groups (refer to
consider the following when working with these FCoE ports:
•
All four FCoE ports in the group are mapped to the same N_Port.
•
You cannot map individual FCoE ports within the same port group to different N_Ports.
•
Any Access Gateway operation that involves moving F_Ports will move all FCoE ports in the
group.
•
All four FCoE ports in a group will fail over or fail back to one N_Port.
