[Users] HP BLc QLogic 4X QDR IB Switch oddness

[Andrei Mikhailovsky]

Hal, 

The physical state changes every few seconds and goes from DOWN/Polling to DOWN/Disabled to DOWN/(something else) don't remember exactly. It just keeps cycling through them. I've never seen the ports in INIT state, which I think it should start with when there is a connectivity. 

Thanks

Hello guys, 

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. 

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: 

State: Active 
Physical state: LinkUp 

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. 

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. 



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 ?

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. 

Has anyone come across this kind of behaviour?

Have you tried reseating your (server) cards ? 

Also, would you comment on the topology ? How large a subnet is this ?
