Based on skimming our old notes, it looks like it worked after we used the ACU to create 2 logicial drives instead of having Intelligent Provisioning partition the drive. Note that Intelligent Provisioning generated the following error, which we ignored (i.e., we clicked 'Continue').
"The configured partition of 92151 MB is less than the minimum size of 180224 MB for the selected operating system. Are your sure you want to continue?"
However, I can't promise that is the solution because the problem seems intermittent; maybe we were just lucky.
Good luck!
