<p class="MsoListParagraph">The kernel fix there is working, but there is a missing OVS service restart, since restarting Mellanox driver openibd required OVS restart.<o:p></o:p></p>

<p class="MsoListParagraph">On our side looks like MOS-cinder added a patch to the cinder package which has a mistake on the ISER part.<o:p></o:p></p>
<p class="MsoListParagraph">We investigated it here and found the cause, the solution is a small fix in the ISERTgtAdm class, which affect only Mellanox. A patch was attached to the LP bug.<o:p></o:p></p>

<p class="MsoListParagraph">This was reproduced twice. Looks like it’s not related specifically to Mellanox flow, but a general MOS issue – mismatching tenant owners for floating-IP and port (services/admin).<o:p></o:p></p>
