Hello,
I have 2 host, one running ESXi 5.1 and ther other ESXi 5.5. I have one host connected to the SAN using ALUA and the other using LSI. The host running 5.5 constantly drops connections to the SAN, to the point where both connections goe dead and only rebooting solves the issue. My question is whether both host connected to the same SAN need to be configured for ALUA in order for it to work properly?
