Hi,

Our proxmox 6.3-3 installation does not detect a qualstar Q24 tape library attached via SAS.
According to lspci the controller card is detected and the st module is also loaded but I have no /dev/st* devices.
dmesg does not show anything related to the tape drive.

Code: 
#lspci -v

I guess it's not really a proxmox issue but a generic debian thing but I have no idea where to debug from here.
We are migrating from freenas to proxmox and since it was working in freenas I guess it's not a hardware issue.
