RE: UPS signal status

[Jerry Adams <Jerry@xxxxxxxxxxxxxxx>]

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.
