Anyone have experience with these 2 Centos Dell PowerEdge 830 errors?
(1) PCIe Training Error: Embedded Bus#00/Dev#1C/Func#4
(2) SATA port 0 not found

I'm in a small training class where the teacher's old computer died.
I told her I'd look at it where those are the two errors on the screen.

Opening the case, I see only this card in a long slot on the motherboard.

I don't know what the card does but it has an SATA cable to each of 4 HDDs.

It seems disk 0 of the four disks is "unknown device" for some reason.

Only 3 of the 4 "Arrays" are found (What is an array? Is that a disk?)

Do you have debugging advice that I can give to this teacher for her Dell?

My first inclination is to think that the card is a raid controller and that the first disk has failed. Part of the "conversation" is to identify each device to the controller. These are smart devices these days. I would check disk 0. The disk itself is probably OK, but its controller may have failed.
