Is there a trick to getting hardware MPIO working on iSCSI adapters in ESXi 6?
I have x2 QLogic iSCSI adapters (vmhba33 / vmhba34) that can attach to a QNAP storage array but the LUN I present can only been seen by one NIC at a time? The LUN was created to allow multiple connections. If vmhba33 is connected, then vmhba34 doesn't see it. If I disable vmhba33 (ie, shutdown the port on the switch) then vmhba34 will discover it. I can't seem to get both NICs to see it at the same time though.
If I create a software iSCSI adapter and bind vmnic0 & vmnic1 to it, then I get MPIO.
There's tons of documents out there about creating multipath iSCSI connections but they all rely on the software iSCSI adapter. I haven't found any good resources for hardware iSCSI.
Thanks!!
