I too am having the exact same issue with my 7101A on 11.5.1, however I don't have Parallels installed. On boot up I get the prompt windows for the unrecognised drives (strangely only 3 window even though I have 4 980 Pros RAIDed), like you I ignore each. HOWEVER, I found an unsustainable workaround which consists of me running the install of the drivers but BEFORE clicking restart to complete the installation my RAID is useable like normal. Appears just as it did on Catalina with all normal functionality. Though I have to keep the 'complete installation' window open as it does not allow you to close without restarting and once I do restart I'm back to square one again.So driver v1.1.26 seemed to be working fine with Mac OS 11.5.1, but today, I updated Parallels Desktop, and it installed something that required me to 'Allow Access' in Security and Privacy. I did so, and restarted. Upon reaching the desktop, my Mac said it did not recognize the 4 980 Pros in my RAID, and asked me what to do. I clicked 'Ignore' 4 times and restarted. Same problem - no RAID access. I checked, and the HighPoint driver was apparently not loading, so I re-installed it, and my RAID immediately appeared on my desktop. Shut down and started up again, and no RAID. Restarted, and still no RAID.
Apparently, the new version of driver for Parallels Desktop is interfering with the HighPoint driver. I cannot report the issue to HighPoint because I was banned from Support. Can someone else with a HighPoint RAID and Parallels Desktop see if they have the same issue and if so report it to HighPoint?
I have been talking to Highpoint support but their suggestions hadn't worked (removing the depreciated kexts and running a command to manually load each time. Behaviour had been exactly the same although coincidentally Apple released an update for Big Sur which I ran and now everything appears to be working as previous (previous to updating to Big Sur).I too am having the exact same issue with my 7101A on 11.5.1, however I don't have Parallels installed.

I've tried contacting Highpoint support with no luck yet.
Edit: Just to say that I only upgraded to Big Sur a couple of days ago so that was what definitely broke it on my end.
I'm running dual 7101-A1's and Parallels 17.0.1. I had to reinstall the driver after upgrading to 11.6, but everything seems to be working fine now. One thing I would suggest is to run the Apple Hypervisor instead of Parallels (you'll lose nested virtualization - if that's needed, this isn't an option). When that is done, you won't need to authorize the kext for Parallels any more. That seemed to be an issue for me.v1.1.26 seems to work fine with Mac OS 11.6. Still no sign of a revised HighPoint driver for upcoming MacOS 12. I keep checking. Anyone out there running Parallels with their HP RAID? I still can't install v17.0.1 (Parallels) without losing access to my SSD7103 RAID.
