Installer ignores Disks and shows 'no supported disks found'

[Retuas]

Hello!

Starting right away with my hardware: HPE DL380 Gen9 SmartArray P440AR Controller HBA Mode with Seagate Enterprise Performance 10K SAS Disks.

In trying to install Proxmox on this Hardware and after booting the Proxmox Installation i can see that Proxmox detects the Disks and searches for isos on them (why?) but then they will get ignored and 'no supported disks found' is shown.

Is there a way to fix this? Can anybody help here?

Thanks in advance

Proxmox detects the Disks and searches for isos on them (why?)

Can you provide a screenshot of that? Sounds very strange.

can you switch your virtual terminal to a root shell and list the disks available, e.g. ALT-CTRL-F2?
