Re: UPS signal status

(Sorry for the delay. Friday appears to be the day the alligators come out and I am up to my keester in them.....)

Not as I understand it. The QUPSDLYTIM is for how long you want the i to remain on battery before shutting itself down. My understand is that if the power fails and IF the batteries report in as weak, the i takes matters into its own hands and shuts down pronto, regardless of the QUPSDLYTIM setting.

Pete,

Isn't that (delay) what the QUPSDLYTIM system value is for? Or have I misunderstood all of this time?

I don't have a monitor program. We get blips frequently. They oftentimes take down our "new and improved" Windows 2003 servers (especially the one running MS-Exchange), but our i5's never hiccup. We did have power down long enough a few weekends ago (we're basically a 10 x 5 business) to drain the UPS, and that shut 'em down flat. But blips don't.

I have a similar problem as Armand and I should probably submit a DCR to IBM because I really don't think it works in a way that is helpful. I think that if a "weak battery" condition is detected during a "power failure" there should be a delay, set by a system value, that allows the i to wait a user defined # of seconds before beginning the power down sequence. An immediate shutdown when a millisecond drop in power is detected just seems silly. Sure, a "weak battery" is unpredictable as a backup power source but when a transient power blip can bring down your system, *that* seems a little anal retentive to me. Give me the option of determining how many seconds the power has to be off when there is a "weak battery" before shutting down.

I know on that we get one message from our UPS to our "IBM i" 520 when there is any kind of a power issue. It could be a total or partial loss of power or any other function that forces the batteries to provide or supplement the power coming in from the power company. A second type of message is received when power resumes to normal.

I am curious why your system powered down instantly. I wrote our procedure (largely because we get a few blips) to notify me of a power issue, recheck in 30 seconds, then again in 5 minutes to determine if power has been restored. At the end of the 5 minutes with no power to the UPS is when we begin to the process to power down the system.
