XCP-NG installer not recognizing logical volume

Trying to install XCP-NG 8.2 on a HP Proliant DL360 G5 with two HDD set up in a RAID 1+0. The controller setup indicates a logical drive of approximately 175 GB which should be plenty big for XCP-NG to install on, but the installer is balking and telling me it cant find a drive with enough space.

This is my first go round with server class hardware but I’m not a complete noob. I know I’m probably just missing something simple. TIA.

That question might be best served over in their forums https://xcp-ng.org/forum/category/4/installation
