Hi Shyam and Jim, Do you know the answer to or can you redirect me to someone that can answer the following:
The user below, Farhan Ahmed, is doing the following with a Equallogic target. On the initiator box he has multiple network interfaces on the same subnet. He then has a iscsi iface for each one that is bound to the iscsi target. So he has run iscsiadm -m discovery -t st -p ip -I his_iface1 If he disables something in the network that affects the default route then he can do: ping -I net_interface $targets_ip but when we try to login a normal session it will fail. See packet #97. In this test he does not run something like route on the initiator box to update the default route. Instead he is relying on the iscsi code's interface binding to force the use of the interface. We can see the iscsi login pdu get sent, but we do not see a iscsi response. From what I can tell we just seem to see a tcp ack. Then later in packet #104 we see the initiator give up on waiting for a login response and disconnect the tcp/ip connection. However, the weird thing is that before we try the normal session login we see in packet #10 that a discovery session works ok in this test. So command #1 works but command #3 does not and between that time he has not done any changes to the iscsi config or network. Is what Farhan is trying to do supported by EQL targets? And is there a way to if the target is getting the iscsi login pdu correctly?
