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><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><br>Thanks<br><br>Andrei<br><br></div></body></html>
