unRAID [6.6.6] cant see alle PCIe cards


Recommended Posts

I am experience a rather strange phenomenon. unRAID cannot see my Chelsio CC2-N320E-SR card.

But if I remove my two VGA cards (GTX 760 & GTX 1060) it can can see the Chelsio card. Not only can see it, but it works as intended.

I have asked around at my work, and possible root causes has arised and fallen. to name a few:

* the PCIe x16 populated by the VGAs will disable the populated Chelsio PCIe. - as my system is a dual CPU system, and the VGAs are on CPU0 PCIe and the Chelsio are on CPU1 PCIe, it cant be related to this error.

* the Chelsio does not get enough power. - my PSU delivers up to 1200watts, and I only draw 600watts, so there shuold be more than enough watts to go arround.

* the PCIe are defective. - I have tried to reposition my LSI card in all slots, all work.

 

My system overview:

unRAID version: 6.6.6

Mainboard: Supermicro X9DRi-LN4F+

CPU: 2x Xeon E5-2690 V2

RAM: 24x16GB reg. ecc

VGA1: GTX 760

VGA2: GTX 1060

NIC: Chelsio CC2-N320E-SR

 

Any thoughts are welcome.

I am grateful for any help I can get to solve this problem.

 

Thanks

 

P.S I forgot to mention that I cant even see the chelsio card in the tools system devices
