Hi,

 

In order to better assist you, would you please let us know which PAC card that you are using? Is this N3000 or D5005?

 

Besides, what type of server you are using for this PAC card? How many PAC cards in that server?

 

Regards -SK

Thi is N3000 PAC Card. We are using Quanta server.

There are two PAC card in this server.

Please find the detailed FPGAINFO output-

 

FPGA port mapping

[root@<Compute_Name> ~]# fpgainfo phy | grep -e "^PCIe" -e "^Port"

PCIe s:b:d.f         : 0000:8a:00.0

Ports Num           : 01

Check FPGA ports status with "fpgainfo phy" command.

[root@<Compute_Name> ~]# fpgainfo phy

Hi @Ravishankar​ I have sent you a private message.

Hi @Ravishankar​ 

Does this happen to SRIOV use case only?

Could you explain the steps you took to replicate the issue?

Yes this happends to only SRIOV port on the FPGA card. This is seen randomly in the Server having this FPGA card.

What are other logs that we can see to get more details of this issue?

Hi @Ravishankar​ 

 

Sorry for the delayed response. May I know if this issue has been resolved?

If not, would you send me the steps to reproduce the issue.
