Just write over the boot record and then put it back later. The Dead Beef part is tough unless you decide to mess with the second boot record and program.
-----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of McKown, John Sent: Monday, August 22, 2005 1:02 PM To: [email protected] Subject: How to easily render a system unIPLable/IPLable I am running some SMP/E jobs to apply maintenance to our "sandbox". It is currently "down". I have emailed everybody that it needs to say down while I do my maintenance. Yes, I generally trust them. However, since I have the "sandbox" OMVS files mounted in order to directly put the maintenance on them, I was wondering if there is a simple, easy to reverse, way to render a system unIPLable? I don't really want to AMASPZAP the IPL text or anything weird like that. I don't want to rename any libraries (such as SYS1.NUCLEUS) because that would "mess up" my DDDEFs. And, just to be weird, I really love the result to be a "hard wait" with a code of 0xDEADBEEF. That would amuse me greatly. -- John McKown Senior Systems Programmer UICI Insurance Center Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its' content is protected by law.
