Oh yeah, forgot about that. Thanks Pasi! Joseph, look in the EQL target logs for something about the EQL box doing load balancing. I think normally we handle the load balancing more gracefully, but we might be messing up. I think if EQL was load balancing in the open-iscsi logs we would see something about getting a async iscsi pdu from the target that asks us to logout. Then when we relogin the target would redirect us to the optimal path. -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
