My solution:

It seems I had a flaky power supply. The drives would spin up, recognize
the power supply is not reliable and then power down. Replacing the power
supply fixed everything.

Other comments:

1. Get firmware updates for the drives.
2. Check out the document by David D. Ward previously posted to sun-managers.
    This document covers appropriate jumper settings.

Thanks for all the replies.
