Description of problem: Create a HW pool, add some storage to it. Try to delete the HW pool. Deletion fails with a server error; it should provide an error message to the user telling them that the HW pool can not be deleted since it has storage attached.
This seems to work now on the 'next' tip. It was probably fixed as a side effect of the controller/error handling refactoring. Setting to 'modified' so it will be tested on release.
