I'm dealing with multipathing issues with our ESX 4.1 and md3000i. I'm looked at the config guides, and they don't indicate that 2 vmkernel iscsi ports are required on the host, but I can't seem to get the multipathing w/o it. Could someone chime in with their config to their md3000i and whether 2 seperate networks are required for multipathing, and if so, then 2 vmkernel ports on the hosts?
Dell recommends two separate networks (separated logically by IP subnet, and separated physically by separate switches or VLANs).
For Dell's recommended configuration, you need 2 VMKernel interfaces.
Follow the MD3000i config document from Dell, it works exactly as it's supposed to:
