I believe I have multipath configured correctly.
I have two ESX nodes running VMware 4.1 and an HP P2000.
When I go into the datastore and select multipath, I have it configured for Round Robin.
I see 4 paths. 2 say Active (I/O) and 2 just say Active.
The 2 Active (I/O) are my first controller. And the two that just say Active are my second controller. I am guessing this is an Active/Active SAN but only one controller can do I/O (own the LUN) at once.
Is this correct? Or should all 4 be Active (I/O)?
Or, should the (I/O) be split across the two controllers?
