Those log files should be trimmed. When log files get that large they discourage people from reading them. This won't really buy you much space back though. A "du -sk * | sort -n" will probably show that "save" has most of the space. This is need to remove patches. HP has a script that can help reclaim some of that space called "cleanup". It became more powerful with HP-UX 11i. If you are running that release, you can try "cleanup -p -c 2" or even "cleanup -p -c 1" if you're feeling brave. The -p is preview so it will only tell you what it would do without actually doing it. If it looks good, reryun the command without the -p.
