As I've written in the past, I have two HighPoint 7101A-1 cards in my 2019 Mac Pro, and an 8TB RAID10 volume made across both of them (eight 2TB drives) using the HighPoint driver/utility. I figured the upgrade to Big Sur would cause some initial issues with the driver, possibly requiring a re-installation. Sure enough, when Big Sur booted, my single 8TB volume was gone and the OS could see the eight 2TB NVMes.
I disabled SIP and reinstalled the HighPoint drivers. After a reboot: zilch. Nothing. The little web-based utility claimed it couldn't connect to the hardware. And interestingly, even though the KEXTs were in the proper directory, they weren't being loaded. I manually loaded them and checked the utility again: nothing.
Nothing I could figure out on my own would bring that 8TB volume back. I'll bet there's a way to do it, but I also always have a handy Time Machine backup. So I let the OS recreate the volume (two stripes into a mirror) and am back up and running if a teeny bit slower.
At this stage I have no idea if HighPoint needs to release new versions of the KEXTs, or if there's some other sneaky trick that we need to do to get the OS and utility to connect to the card(s).
