Hi, good findings!
We had a similar problem today, but only one FC adapter on one host (out of 16 identical ESXi hosts, each with a dual port "ISP2532-based 8Gb Fibre Channel to PCI Express HBA") reported this error "a minor problem that is causing limited interference".
The difference in our case is, the FC HBAs are used for storage connectivity, so disabling the driver is not an option?!
And it's not just a false alarm that could be ignored, in vSphere Client it was also visible that one adapter had no connection, thus no redundancy to the storage anymore.
A reboot of the ESXi host fixed the problem so far, but it's not a solution if that happens again. Especially because in vShpere Client there was NO alarm (hardware status all green) in this case! Only HP SIM reported the disabled adapter!!
