I recently purchased a used ibm x3550 server with two 2.5" SAS hard drives included. When I boot the server it doesn't recognise them. I get into the bios and I can't see them there. I try to install windows and it doesn't show any hard drive.
When I open it, everything seems to be correctly connected. I think the problem might be come from 3 different sources: 1. the disks are defective. 2. the disks are not properly connected to the motherboard. 3. I need to upgrade to bios. All 3 of them seem unlikely. Otherwise the machine can see an external drive connected to the usb or a DVD.
I'm stuck at this point, I don't know what would be the most cost effective solution to diagnose my issue.
