I'm told that we cannot do Multipath I/O on our iSCSI SAN on RHEL with 2 network cards. I could use 1 network card, but need an HBA. Is this true? Do I need an HBA, or can I do Multipath using 2 NICs? We're running RHEL 4 and CentOS 4 and 5 servers on this network.
I have been reading through the device-mapper documentation, but I have not found anything (unless I'm not clear on what they're saying). Eventually I will give it a try but I haven't had the time to fiddle so far.
Thanks, Scott
