Thanks for your help. It turns out it’s a Microsemi PQI adapter.

I built a new kernel based on 4.19.1 and enabled

Device Drivers -> SCSI Device Support -> SCSI low-level drivers -> Microsemi PQI Driver

when running make menuconfig and now it works.

I’ve been trying to image an HPE DL360Gen10 Server. The system has a Smart Storage PQI 12G SAS/PCIe controller. Adaptec based.

When trying to do a deploy or inventory, it says “Cannot find disk on system (get HardDisk)”.

If i boot the machine into debug mode, it can see the controller (lspci and lshw) but there no drivers are loaded for it.

Running FOG 1.5.4. I’ve tried many kernels. All kernels expect 4.18.11 seem to hang at loading init.xz

Ubuntu 16.04 sees it fine and can boot from it. It shows up as /dev/sda and uses the aacraid driver.

Any help, suggestions, ideas would be appreciated.
