Hi - I am running into problems utilizing two NICs in an iSCSI setup for multipath IO. The setup involves a Linux server (Ubuntu 9.10 Server) with two Broadcom NetXtreme II GbE NICs connected to two separate switches on a single subnet, which is dedicated to EqualLogic SAN access.
I have setup two iface definitions using the following steps. - iscsiadm -m iface -I eth4 --op=new - iscsiadm -m iface -I eth5 --op=new - iscsiadm -m iface -I eth4 --op=update -n iface.net_ifacename -v eth4 - iscsiadm -m iface -I eth5 --op=update -n iface.net_ifacename -v eth5 I have also tried specifying the MAC addresses explicitly with no change in behavior. Discovery was performed with the following command and worked as expected, generating node entries for both interfaces. - iscsiadm -m discovery -t st -p xx.xx.xx.xx:3260 -I eth4 -I eth5 Up to this point everything looks good. And I have no trouble logging one interface into the desired target. However attempts to login the second interface always result in a time out. The message is iscsiadm: Could not login to [iface: eth4, target: <target>, portal: xx.xx.xx.xx,3260]: iscsiadm: initiator reported error (8 - connection timed out) The problem is not specific to one interface. I am able to login with either one. I just can't seem to login with both at the same time. I am using the open-iscsi package that ships with the Ubuntu distro (open-iscsi 2.0.870.1-0ubuntu12). I have another server on the same network, with identical hardware and iSCSI configuration, that is working properly. The only difference is that the other server is running CentOS 5.4 and using the initiator that ships with that distro (iscsi-initiator-utils 6.2.0.871-0.10.el5). If anyone could provide any guidance on how to further diagnose, and hopefully solve, this problem, it would be greatly appreciated.
