Wouldn't it be good if you can post the cause and solution? It may be helpful for others.

Sorry.
I was embarrased that I didn't initially know what I was doing.
After reading the book a little more I figured out I had to set the location parameter default.

So, as everyone else probably knows, you need to issue:

configure channel 1 device type disk format '/export/u03/hot_backup/backup_%U';

I assumed the defaults were set up and they were not.
