Troubleshooting Fx Port Connectivity

Counter Values (5 minute averages):
Usually a port in this state cycles between the initializing state and the off-line state. If this the error,
verify that the switch port is configured as an F port. A port that is mistakenly set to be E port could
cause this error when connecting to an N port. If setting the switch port to autodetect mode still doesn't
resolve the issue, try to statically configure the port type in order to match the Nx port behavior with
respect to loop or point-to-point initialization. There are some limited case in which the port type auto
negotiation could not work properly for incompatibility with some old HBAs. (The automatic detection
for the port mode is not applicable on an OSM module where at maximum one TE/E port can be configured
per quad.)
If after having statically configured the port mode, it still doesn't come up, verify that the HBA is
working properly and possibly power-cycle the HBA (i.e. booting the server or resetting the adapter).
To check whether a FLOGI is issued to the switch during the Fx port initialization, the fcanalyzer can
be used.
In the example below, the fcanalyzer tool has been used with the necessary filtering to capture the FLOGI
sent by the N port. Refer to the Cisco MDS 9000 Family Configuartion Gude for more information.
