Gotta find out what the problem with the SAS cables is now, but the FC topic has been solved by just switching ports. The problem was an incompatibility with the FC SFPs I got and the UTA extension card, they do not > work together and have to be deployed in the onboard UTA ports.
Yes, PCIe card and on-board ports use different SFP. I wish HWU also displayed original manufacturer model, because for all I can tell there are no NetApp part numbers on them (at least in the past, may have changed today).
Nice you have this sorted out.
