I am currently deploying a Cisco UCS mini solution with two FI 6324 modules. I have set the first two ports in FC mode and configured the FI modules in FC switch mode. This is a smaller solution with an EMC VNX connected directly to the FI modules. I have followed the guides and I have successfully configured all connectivity.
I have however noticed that if there is a sync or link loss on the FC ports, the ports report an error and the port stays down. This could for example be a firmware upgrade on the storage system which will cause a brief link down status. Another example is to simply replace a cable, causing a short time of link down. I still have redundant paths, meaning I do not get a service disruption as such, but the only solution to bring back full redundancy is to manually disable and then re-enable the FC port in the FI module.
I don't have a lot of experience with Cisco as a whole, but I assume this behaviour could be by design. The FI module detects an excessive number of errors and disables the port. Is this assumption correct? If so, can I configure the port error threshold or the number of attempts to re-establish connection? I would like to automate the operations as much as possible.
