If you assign a subnet to each interface on the RAID, and assign one of those subnets to each interface on the host, you will naturally get a fault-tolerant path between the host and the RAID. You just need to probe each RAID IP once. I think I asked before: What type of hardware RAIDs are these, exactly? dm-multipath is actually very generic; it might "just work" even if your vendor has their own proprietary software. Port bonding is still an option, but thinking about it some more... Unless your RAID also supports bonding, I am not sure it simplifies your configuration at all. You will need one iSCSI session for each IP address on the RAID whether you bond the ports on your host or not. So bonding only simplifies things if you can do it both at the host and at the target, and even then (a) it will be hard to get good load balancing and (b) you will be stuck using one (non-redundant) switch. - Pat -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
