This is in a Ultra 2.
When you delete a LUN other than number 0, Frontview tells me to type "DELETE LUN" to, well, delete the LUN. That won't work, however, and Frontview helpfully tells me to type "DELETE LUN" again. This is in error. To get through this screen, you will have to type "DELETE ALL LUNS" even though you only want to delete the one. The result is that only the LUN you want to be deleted is, though, so the bug is solely in the checking for the typed-in phrase.
