Change Cisco 9148s F port into FL port failed
Hi, everyone,
I am trying to configure a Cisco MDS 9148s fiber channel switch. Everything looks good:
For Interface fc1/11 and fc1/12, each has fiber cable connected to the storage HP MSA 2052 controller( The MSA has two controller:A and B)
Based on my past experience and this link below:

![Screen-Shot-2018-01-27-at-9.34.54-PM.png]()
The fc1/11 and fc1/12 should be configured as FL mode instead of F mode though the Switch auto negotiated into F.
Now I am trying to change it from F mode into FL mode:
The service obviously was interruped.
When I set the mode back to AUTO, the service was recovered.
My questions is: Why would the interface fc1/11 and fc1/12 become "notConnected" after changing them into FL mode? isn't FL the right mode for these two interfaces? (because they both are connected to the controller of the storage.)
The reason I want to do this change is becaues the MSA 2052 only see 5 of the HOST WWN, but I actually connected 10 servers to 4 switches, should have 20 HOST WWN show up in the MSA 2052. I feel the fc1/11 and fc/12 interfaces might be the problem because my old SAN which use two MDS 9124 configured fc1/7 and fc1/8 as the FL mode.
Anyone has experience to configure both this Cisco MDS 9148s and HP MSA 2052 storage?
