Hello everyone
I caused a short circuit on the cable of the battery of my raid controller. Then the battery burned out and the raid controller was temporarily (approx. 20 minutes) not displayed via IPMI. Now the raid controller is back and the raid is fully functional according to the data of IPMI. Unfortunately, the server won’t boot from the raid. (had to set some settings correctly in the BIOS so that it was even recognized as a bootable medium) The raid controller only boots in legacy / bios mode, although UEFI has always worked so far (is also necessary because it is Windows Server 2019 DC in GPT directly on the Raid installed). The Windows Boot Manager doesn't appearts in the boot order. Does anyone know how I can “force” the raid controller to boot in UEFI mode? Switching to Uefi mode manually in Uefi/Bios only caused the controller to disappear from the list of bootable devices.
Thank you for help!
Regards
Jan
