I connected a unix host in a SAN switch. The port connected as L-port and not as F-port. What is the reason ?

Can someone help me ?

Hi,

 

First of all your driver of the HBA, lets the hba attempt top log in as a loop port, that needs to be changed to fc-fc or point-to- point connection.

 

Second your switch port is not set to G-port.

Initially when an initiator logs in, it tries to login as loop, if that times out it tries, E-port then F-port. But since your hba driver is set to loop it logs in as loop.

You can force the switch port to G-port, which will stop the initiator of login in as a L-port, and tries immediately E or F-port.

Command would be: for example:

portcfggport 1/3, 1

Thanks for your reply.

 

It seems that the problem is in the conf of the hba that is set to loop. I am waiting the Unix´ support answer.

There may be other reasons. See here: http://www.erwinvanlonden.net/2015/05/port-stuck-in-l-port-mode/
