Hello,
my MellanoX ConnectX-3 worked well the last Months. But last month i installed a HyperV Machine with an external Switch connected to one of my four Intel i350 Nics.
Since then my Mellanox 40G connection doesnt work any more.
The Server reports a IP Adresse. But i cant ping it,
It also says it is connceted but has no Internet.
Windows tells the network is not identified. But when i open network in explorer i dont get the chance to switch to private network.
I use a Supermicro M11sdv-8ct-ln4f board. It is a bit tricky with this board. I only get into bios when i remove my x8x8riser with the mallanox and my samsung PM1725 SSD.
The local Server Manager reported Problems with SR-IOV initialization. So i enabled it in Bios and turned it on in Firmware. but it didnt solve the problem. The next boot it reported Roce issues. driver loaded v1.5 and system required v2. so i switched to v2. the next reboot the mellanox had no valid IP-Adress. so i switched back.
And as soon as i disable SR-IOV in the driver menu i also lose my normal IP Adress.
But right now i am out of luck and need some help.
Any idea how to fix this?
Thank you in advance!
