Re: Using failover with differing EUI / IQN values

Possibly not. I've seen the same disk receive different SCSI Ids when exported using stgt (linux userspace iSCSI target) and iscsitarget (linux kernel iSCSI target). You need to try it out. If /sbin/scsi_id outputs the same value at the initiator for both LUNs then multipathd will consider
