I don't usually get stumped this bad, but...

I am repurposing a T340 that previously had NOT been setup as RAID. I did a retire/repurpose wipe through the Lifecycle Controller and then configured the server as RAID 10. It has four (4) Crucial by Micron 2.5-inch SSD drives. The RAID configuration goes fine and I end up with a virtual disk just over 1.5TB as expected. When I try to install Windows 2019 from a USB/ISO it does not recognize the virtual (or any other) drive. So there's nowhere to install the OS.

Everything I have read says I need to put drivers for the disk on my OS installation media, but I have been unable to find the right driver that will cause the OS to 'see' the virtual disk. BIOS, iDRAC, Drivers, etc are all up-to-date. Any help greatly appreciated.
