VRTX with M620 PCIe Training Error with Similar PCIe NICS
I have 2 Mellanox ConnectX-3 PCIe cards on Fabric C slots in the VRTX Chassis. I have 2 M620 blades, and I can power on only 1 blade at a time with 1 active Mellanox ConnectX-3 PCIe card. When I turn on a 2nd blade, I get a PCIe Training Error for the slot that the PCIe card is on.
If I power down the blade with the active Mellanox ConnectX-3 and then power up the other one - I dont receive the error.
Essentially I unable to get both blades to work at the same time with 2 identical ConnectX-3 PCIe cards.
The M620 (2.7) is on the latest bios.

Hello
I think the mode of the PCIe slot is configurable. I suggest checking the CMC to see how the PCIe slots are configured. Also, check the logs for any power issues. There may be limitations to the number or type of PCIe devices you can have installed based on the power supplies. You can find documentation on the chassis support page.
