Hi, thanks for your reply.
It's an IBM ServeRAID M5015, which I understand to be an LSI 9260-8i. I've now got the CIM provider and driver installed (as below) but still no luck. I can resolve the ESX servers from the Windows host without issue but still unable to discover the ESX server in MSM (15.03.01.00). I also can't telnet to the ESX server on ports 3071 and 5571 from the Windows server, which makes me think it's not listening on those ports. Have I got the wrong driver vib maybe?
