We had serious power issues for a few years while the surrounding roads were under construction. The APC Automatic shutdown process built into the parachute software (donno if this is what it's still called) seemed to work well enough. We never had any issues with UniVerse shutting down or restarting afterwards.
We utilize a generator for short outages, but usually the heat gets to a point where we have to shut down after a few hours anyway. -----Original Message----- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Arnold Bosch Sent: Wednesday, July 20, 2011 6:41 AM To: U2 Users List Subject: Re: [U2] Universe Server & Hibernation Many thanks for the responses :) - lost of food for thought! George, Thanks; I'm aware of the UPS being able to trigger processes; in fact I'm working toward a "control" system that will in future help to handle such incidents; there is a handful of less critical servers involved as well. Wol - the hibernation is not set up yet; and yes; I want to suspend the entire server and operating system to disk - no VMs involved. Our UV server is the server least often shut down or rebooted; to the point where I actually delay OS patches for months on end; having a 100% uptime of 6 months on the UV server is nothing new here. In fact last week's incident was the first in 3 years where this server went down without pre-scheduled downtime. John, a generator is high on my priority list. Proposals and funding for one have been repeatedly rejected during the last couple of years by my directors. We have invested heavily in wireless technology in our warehouses in the last year though, and I'm busy preparing new proposals which should be more open to acceptance, as power outages will have a much bigger impact on our business operations than in the past. We don't have a large user base - just 120 users at present, but that incorporates a whopping 50% growth in just the last year; it's been playing havoc with capacity planning and licensing! Thanks Stuart - it looks like I'll have to do some testing then. I'll just install a copy of UV on a test machine and restore a backup to it and run the tests within the 30 day licensing grace period; I really feel Rocket wouldn't bust my butt for a once-off test like this. If anybody from Rocket reads this, I would appreciate your comments before I do it though. If/Once I'm happy with the software tests, I can do a controlled test on the actual server to check for hardware related issues. There are two other small UV sites here in Namibia that may also benefit from this "localised" experience - I'll post feedback on the test results. Ross, thanks; the processes run in serial from a paragraph list - unfortunately it needs some user data inputs to start up thus the need for a telnet session on the server console to start it; we learnt years ago it's not good to run this lot from a networked session! No SAN / NAS - just a proper RAID system in the server itself. The console telnet session is my main concern though... I might have to see if we can start the processing off from a local UV shell; that might be more feasible than a local telnet session.
