I currently have my UCS environment setup with a single FC connection from 6248 to Nexus5548UP
UCS-A ------> 5548-1 (VSAN700)
USC-B ------> 5548-2 (VSAN701)
UCS side looks like this:
Nexus 5548 port looks like this:
interface fc2/7 switchport description FC Uplink to UCS-6248-A switchport trunk mode off no shutdown
If I were to add a 2nd (Or 2nd, 3rd and 4th) link between each FI and it's respective Nexus switch, is there any programming I need to do specifically on either the FI or the Nexus5k to prevent some kind of unforeseen FC disaster?
In the newer firmware, You can try resetting connectivity of HAB(one at a time) from the equipment tab instead of rebooting. After resetting HBA initiator will FLOGI into Fabric Interconnect, pin to available uplink.
