[opensuse] apcupsd Configuration
Hi everyone I have 3 servers. Let's call them A B and C Server A has an APC BR1500GI connected via the APC RJ50 to USB cable. I wish to set up apcupsd so that when the power goes off, Server A tells server B and C to shut down. Once they have shut down then server A should shut down. So effectively Server A is the 'master' and B/C are 'slaves' I understand this is possible but I have never had to do this before. Has anyone got a similar setup? I also understand that it is possible to have the UPS shut down automatically after the apcupsd 'master' shuts off and then the UPS will turn back on automatically when the mains power is restored. If so this would be ideal because then I can just set the BIOS on the servers to turn on after power is connected and have everything come back on automatically too. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Yup, sounds much like ours. We monitor three UPS'es (APCs in parallel) with SNMP. Every machine has a apcupsd client that talks to the master/server (who talks to the UPS'es).
I also understand that it is possible to have the UPS shut down automatically after the apcupsd 'master' shuts off and then the UPS will turn back on automatically when the mains power is restored.
I would have thought the UPS will always come back on when power is restored?

Basically, in this scenario, server power should be set to "always on". -- Per Jessen, Zürich (9.8°C) http://www.cloudsuisse.com/ - your owncloud, hosted in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Ah ok so I am on the right track. That's good. :) If possible, can you please send me your config so I can see how it is set up?

I read that only when shut off by the USB / serial, not when shut off manually by the power button. But I have not tested this yet.

Basically, in this scenario, server power should be set to "always on". Yep exactly.
Although at my old job we had so many servers that used to trip out the ring main so we had to get one of those PSUs that turn on one at a time every couple of seconds. Good times lol -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Sure, I'll email it.

I don't think we actually do that - actively shut down the UPS. I wonder if maybe we should.

Yes, start-up surges can be an issue, but as you say, staggered power-on will solve that one. -- Per Jessen, Zürich (8.1°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Also, the apcupsd manual is usually pretty good: http://www.apcupsd.org/manual/ -- David C. Rankin, J.D.,P.E. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Not all do, and some can be configured somehow to do so. -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)

Have a similar setup here, but I'm using nut for it. The master watches the actual UPS, the other computer(s) only run the monitor part that connects to the master. Nut can also use/talk to a running apcupsd, but it does as well have its own client driver for APC. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
