I replace Motherboard, then i face issue in Dell R710 when i connect my server to SAN through SAS cables then shows following error and also not show raid controller.
Bus 4 Device 0 function 0 slot 5
Bus 3 device 0 function 0 Integrated RAID
and when i remove NIC then it boots normally.
also i replaced NIC card and RAID controller but have same issue. Currently NIC card is newly installed and RAID controller is old.
BIOS and RAID controller firmware are updated.
I think it is due to conflict between NIC and sas cables or something help.
Please help to resolve this issue
