Fibre channel port remains in initializing state
A fibre channel F type port does not come online and is stuck in an initializing state.
The show interface fc <slot/port> command displays the following message.
A Fibre Channel port goes into the initialization state after a successful completion of link-level
initialization. For F type ports, the next step is to complete the FLOGI (fabric login) process. The port
remains in the initialization state until the FLOGI process completes.
Possible Cause
The port is up because the link partner has put itself into a bypass mode.
Solution
Use the show hardware internal fc-mac <slot-number> port <port-number> statistics command to
check whether the Class-3 input counter is increasing after the successful completion of link
initialization.
Example:
switch# show hardware internal fc-mac 2 port 1 statistics
