Sorry for the delayed Summary:

thanks go to Jae, Buddy, Lusty, Alex, Yann, and Alouache among others.

The answer was twofold

1 I had to run installboot against the mirror root drive. The Online
disksuite online manual only mentions installboot for x86 systems.

2 I had to run show-disks at the 'ok' prompt, then select the right path,
then do my nvalias command from there.
The path I was given from the show-disks command is different from the path
I get from following the online manual instructions that have me do an ls
-la on the raw device of the mirror disk.

thanks again for your help and my original post is at the bottom
