here we go! now we are getting somewhere!
can you please post the output of ibstat command (or ibv_devinfo)
who did you buy those cards from (once you tell me that, i will tell you if you are able to get a newer firmware).
FDR Vs FDR10 - things that could happen:
- old FW - you always want to be on the latest for both your HCAs and the switches
- the correct cable - make sure your cable it certified for FDR.
