This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unfortunately unable to address this request at this time. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. I am going to resync the iscsi package to the upstream/rhel6 version, so this will get brought in. Thanks for the patch and report.

* Previously, the open-iscsi administration utility (iscsiadm) sent incorrect initiator task tags (ITT) when encountering a multi-PDU This caused the discovery to fail. With this update, the ITT initialization and allocation sends the correct tags and iscsiadm works as expected. (BZ#633122)
