It sounds like you did not bind that iface. Does: iscsiadm -m node -P 1 show records for both ifaces? You should have done something like iscsiadm -m discovery -t st -p ip -I be2iscsi.00:17:a4:77:10:01 -I be2iscsi.00:17:a4:77:10:00 or iscsiadm -m discovery -t st -p ip -I be2iscsi.00:17:a4:77:10:01 iscsiadm -m discovery -t st -p ip -I be2iscsi.00:17:a4:77:10:00 -o new > > I have other servers where I'm only using a single FlexHBA (be2iscsi) > and they are having their own troubles.

Maybe the LeftHand target needs some blacklist entry in the scsi mid layer to scan for devices properly. -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
