Thank you to

Darren Dunham
Douglas Hagan
Thomas Wardman

who responded to my plea for help. I owe a particular debt of gratitude
to Thomas Wardman for patiently answering my extremely naive questions
about using the "drives" that Raid Manager produces.

The answer to my original question (as shown below) is that Raid Manager
was not giving me conflicting answers--I was just misinterpreting them.
healthck gives you information about modules, and lad gives you information
about LUNs, so I was comparing apples to oranges.

Once I was able to successfully create and delete LUNs at will, my only
remaining question was "what do you actually USE", which all of Sun's
documentation was maddeningly silent on. The answer is that Raid Manager's
LUNs show up as drives that you can "format", "newfs" and all the normal
things, using the devices that appear in the /dev/rdsk and /dev/dsk
hierarchy after you've created the LUN.

Thank you sunmgrs for saving my butt only days before my vacation starts!
