I have seen it happen. I did the data bases and CICS regions first then brought the software and operating system. The hardware just lost power but when the power came back on once the DASD went it check eveything came up clean.
From: Darth Keller <[email protected]> To: [email protected] Date: 12/03/2010 11:45 AM Subject: EPO's (Emergency Power Off) Sent by: IBM Mainframe Discussion List <[email protected]> An interesting question came up this morning - all your multiple power sources have just failed. Your generator(s) started but, for whatever reason, have also failed. You're now on battery power and have 23 minutes to power everything off as gracefully as possible. Do you have procedures in place to do it? I don't even want to think about all the open-systems stuff, my head would explode. But I don't think this is a trivial exercise even from the mainframe side. I'm thinking you almost have to think about this in the same way you would approach planning a DR event. Maybe you have a couple of scenarios - 1. I know I'm going to lose power in 3 hours. 2. I know I've only got 23 minutes & the clock is already running. Do you get as much of the software shut off as possible & just let the hardware take care of itself? Do other companies have plans in place for this? Is it reviewed with some frequency? Pretty hard to test unless you have your own DR site, but do you at least do periodic walk-through's as an exercise? Do you have or need a procedure on how to restart after an EPO of any duration? Have I found a new career path or should I just ask for my medications to be adjusted?
