My setup : small home server with Asrock H67M-ITX, CPU : i3-2120T, PERC H310 RAID with 7 disks all passthrough (I use MDADM for the raid functionality). The system (Ubuntu 20.04) is on a SSD connected to the MB SATA.

Just got a new CPU : E3-1275 v2

I did change the CPU and to have it work, I had to update MB BIOS from v1.30 to v2.20.

Now, when I arrive in Ubuntu, the disks connected to the LSI H310 are not visible at all. the LSI BIOS shows the 7 disks properly.

I have no idea where to start looking. How should I start debug.

Should I update the LSI BIOS too?

Edit 1 : output of lspci shows the LSI card (3rd from the end)

  • Ended up being some sort of bad connection in the SAS/SATA cables. I took the Adapter out to log in the serial number, when I plugged it back, it worked flawlessly.

The PERC H310 is a RAID controller. In order to use the disks you've connected to it, you must set up virtual disks either in the RAID BIOS, with the MegaRaid Storage Manager for Linux which runs on the Linux desktop GUI, or with the MegaCli command line tool. The virtual disks you set up will appear in Linux as /dev/sda, /dev/sdb et seq.

First thing first. Recheck all the connection.

In that case, it was most likely a bad connection somewhere.
