I assume you are running in an LPAR. If you don't restrict access to the devices Linux can see then it would be possible for non-Linux disks to be corrupted either by accident or by malice. The dasd= boot parameter isn't sufficient to restrict the determined vandal.
If you're running under z/VM then this is not a problem. Neale On Mon, 2007-04-09 at 15:57 -0400, Frank LeFevre wrote: > We are having an internal debate here.
