<div><div style="font-family:arial,helvetica,sans-serif;font-size:10pt">Hello guys,<br><br>I was wondering if anyone on the mailing list has experienced an odd behaviour with HP BLc QLogic 4X QDR IB Switch (505958-B21)? I've tried to get HP to solve this issue, but it resulted to HP basically saying that they do not have Infiniband specialists who could help me.<br>
<br>My problem is that every time I reboot the blade servers which are connected to the above blade switch the switch ports take ages to Activate. The time it takes when the servers have:<br><br>State: Active<br>Physical state: LinkUp<br>
<br>is random and varies from several minutes to over 10 hours. I couldn't find a correlation or any consistency between the servers or switch ports. The same server could connect within minutes after a reboot, but could take hours following the next reboot. <br>
<br>However, the server which are connected to the same switch with a cable (not interconnected blade servers) do not have this issue and get port state Active in seconds every time.<br></div></div></blockquote><div>What is the physical state of these ports when they're not active (on both the switch and server side) ? Are they LinkUp or something else ?</div>

<br>I have installed the latest available firmware and I have tried chaging blade mezz cards, IB switch and the blade enclosure, different versions of OFED / opensm. It stays the same.<br><br>Has anyone come across this kind of behaviour?<br>
