MP 7,1 OWC Accelsior 8M2 - 7,1 Startup issue

[RossHolter]

I installed a new 16T OWC Accelsior 8M2 the other day, configured all 8 as Raid 1+0. I was very pleased with how quickly it wrote 2.5T of files, and even worked from it for a day.
After shutting down for the night, the Mac Pro seems to not be able to locate the startup disk with the card installed. Removing the card allows startup as usual. I've found it tough to find any documentation on this issue. Has anyone experienced this before?

I have been following a similar issue with the same product for the Mac Pro 14,8.
Not sure if these are the same problems or not? OWC have released a statement about it here. Sounds like it’s a MacOS issue and there will be a future fix.
