dell poweredge pcie training error, what to do?

Solution 1:

Having the same “PCle training error: Internal Storage Slot”. I replaced one of the two capacitors on the PCIe RAID controller that was showing signs of breakdown (expanded housing). 1500uf @ 6.3V. The system now boots and has been running for more than 24 horus.

Solution 2:

We managed to get it booted by turning it off, opening it up and checking the riser/pci, etc. card connections and re-seating them.

We had also tried several power downs, restarts, and removing the newer drive.

Solution 3:

dell poweredge servers are configured with only PCIe Gen 3. if your card is Gen2 or Gen1, then you will face training error.

check with your PCIe configuration. If it is FPGA Configured PCIe then check the configurations and bit file which should be strictly Gen3 only.

we too faced that issue and finally my friend find it.
