Okay… I may have solved this at the end of the day, finally.
I believe it was a sequence of a few items not matching up once I tested certain phases. In the end, I had to switch the boot priority so that the drive with the OS had priority over the data drive. I tried this earlier, but it was after already moving past SANBOOT and when looking into EXIT as an option instead. Now that I have corrected the drive and changed the boot priority, SANBOOT is functioning as intended. I will do a few more tests before I officially resolve this, so I will post back by tomorrow morning on my results - time is limited today.
