SLES 10 iSCSI timeout after load balancing request when using the native open-iscsi

This article provides information on what to do if a SUSE Linux Enterprise Server 10 using native open-iSCSI time outs after an iSCSI load balancing request.

Modify the /etc/iscsi/iscsid.conf

To improve this situation, there are two modifications that can be made to the /etc/iscsi/iscsid.conf.

1. If your discovery is password protected, provide the authentication information to iscsid by adding your password information for the discovery to the end of /etc/iscsid.conf file
   • discovery.sendtargets.auth.authmethod = CHAP
   • discovery.sendtargets.auth.username = <username>
   • discovery.sendtargets.auth.password = <password>
2. Then add the following 2 new entries to give a little wiggle room with connection timeouts on load balancing activities.
   • node.conn[0].timeo.noop_out_interval = 10
   • node.conn[0].timeo.noop_out_timeout = 30
