so I have a bunch of servers at work that are on DUAL UPS's (1 per each of 2 power supplies). Its mostly HP gear, but also some Sun and IBM. Ideally I'd like the system to not go into shutdown unless BOTH UPS's that a particular box is plugged into (there's actually 4 UPS, 2 per each of 2 racks). Has anyone ever configured anything like that with NUT or whatever?
Right now, I'm running without any UPS monitoring software, as the whole building is on a generator that comes on 60 seconds after a power failure, so my 7kVA(!) UPS's don't see much use, and also I just installled these new racks and UPS's and haven't really had the time to sit down and figure it all out.
Nope. I'd think to have something that checked both UPSes, and if both of them were showing no line power for over x sec (60? 70?), start a shutdown.
Here, as I just mentioned, it's only a second or two, so I have to edit /etc/apcupsd/apccontrol to change SHUTDOWN to SHUTDOWN=/dev/null
