Bus 3 Device 0 Function 0 Integrated RAID

Hello.

During POST, this error message pops as a result of certain adapters requesting huge amount of option ROM space that uses all available memory for other installed PCI adapters and on-board components.Try booting the server with the RAID controller card removed and see whether the error is persistent. This error is also not motherboard related but rather imposed by the BIOS. Also consider having the BIOS, NIC and DRAC firmware up to date.

Hi

I will try it but now i cannot afford downtime again and again, Just to confirm what if the issue still exist what can be solution then and what if this issue is vanished.

Kindly share the solution for the both condition so i can close the call in one go rather than take down time again and again.

In case that the error persists with the controller card removed, you can either;

• Disable on-board components not being used e.g NICs in BIOS Setup (F2) in order to de-allocate memory space to compensate depletion of BIOS option ROM by these adapters or
• Enter the NIC BIOS and disable option ROM on every NIC to avail more memory

This could be same as i run the server on minimal post but still i am facing issue on minimal post. 

one more thing issue is on new Motherboard while server is working properly on old Motherboard.

Try the above options with the new motherboard and see what you get.

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

What SAN is the server connected to? Did you try disabling the Option ROM on the NIC?

R710 has up to 4 PCIe slots and since the error shows on PCIe slot 5 when the server is connected to IBM SAN; I advise that you engage with technical support for your SAN for best practices when connecting to server.

Hi 

Thanks for support.

I "disable boot" of all slots. Now server is working fine. It seems that server was going to boot from SAN. If there is any other option than this than please advice or any settings in BIOS so i can also check this.
