I hope someone can give me a hint on an issue I have with iSCSI. I have a FreeBSD Server (the iSCSI initiator) which connects to a Dell Equilogic RAID (the iSCSI target). So far no big deal. But... The Target has one IP to connect to but in reality it has 8 interfaces with different IPs for traffic shaping. So. The initial connect to the pool-ip will result in a connection to one of those 8 ips. Every now and then, the RAID (target) shifts the interfaces. That will result in a message that the the target has moved to another ip... And that is where shit happens - My FreeBSD initiator drops the target completely (With a warning " target requests logout; removing session")... Bad thing :-) I don't know where to look. Is it multipath? MPIO? Any hint is highly appreciated :-) Cheers!
