If you have more than 1 disk controller on the systems (I think 
not on 515s, but can't recall), you could take advantage of Disk 
Sanitizer PRPQ (product 5799-SD1).  Or it you can temporarily 
mount the disks behind a controller on a functioning system and 
perform the sanitize there.  You can use disk sanitizer to clean 
the disks to DoD satisfaction.

My approach to getting the system to the point where only IBM 
licensed software and default user profiles are on the system, I 
would remove user profiles except IBM supplied defaults, all 
device descriptions, all controller descriptions, all line 
description, authorization lists, user libraries, directories in 
the IFS, etc.  Once everything has been deleted, I'd do an option 
22 from the save menu.  If you opt to use the disk sanitize, 
sanitizing would happen here.  The last step would be to reload 
licensed internal code with an inialize the system option and 
reload the IBM stuff.
