We had similar issues Reported.
We had Fabric A and Fabric B which has MDs 9710 on each side. FI-A is connected A side MDS and Fi-B is connected B Side MDs.
On A side we had 5 members of Port channel out of 6 Ports went offline. This has caused due to Discards reported on switch and error disabled. We have situation where the VHBA on the UCS Blades have Disabled state/Offline. The server VHBA were only brought online post reboot of the Blades. Trying to understand why should VHBA should go down on multiple Blades in Multiple Chassis in same FI environment.
