Port stuck as G-port

Hi

I have a customer with a 3par storage connected to a B 6505 v7.4.1a

16 Gb connection

After FW upgrade on the 3par the switchport is stuck as a G-port

We have tried'

1-replacing sfp in both ends

replacing cable

Tried fixed speed both 8Gb, and 16Gb

Tried another port on the switch

Still same issue persist

There is a16Gb SFP installed in the switch of model QK724A  

I will try to install a 8Gb sfp to check

 

Any tip ?

Re: Port stuck as G-port

Hi Thomas,

 

The 3PAR is port 6. Do you see any physical level issues on the port (portstatsshow) or on the 3PAr port (fcpRLSprobe/fcpRLSshow)?

 

What kind of error messages to you see in errshow at the same time as you bring up the 3PAR port?

 

From the fabric log (from port 6) and portlogdump (port 6 only), it look like the switch is treating the port as an E-port.

Have you tried to disable E-port support on the port, e.g. CLI  "portcfgeport 6 0"
