Nut upsuser - Dec 2016 - NUT Client shuts down when performing runtime calibration on APC UPS

Hello,

I am using an APC UPS (Smart-UPS 2200 RM) to secure my SAN. The SAN runs on
FreeBSD 9.1-RELEASE-p5 and is using NUT 2.6.5 version 2. Since the UPS has also
a Network card AP9630 I am using the snmp-ups driver to connect the SAN to the
UPS for signaling.

Last week I need to change the battery pack and then I needed to perform a
runtime calibration. I used the web interface of the AP9630 card to start the
runtime calibration. However, after 2min. of runtime calibration the SAN shut
down!

This is because the UPS status goes "On Battery" during runtime
calibration and this is the signal for NUT to shut down the Client. However, I
know, that there is another status you can get via snmp that gives the
information, that the UPS is on battery because of a runtime calibration running
and not because of a power failure. Does NUT get this additional information and
uses it to discriminate between a real "on battery" state and a
"runtime calibration" state? Or do I have to configure NUT in a way,
that it work correctly and does not shut down my client, when the UPS does a
runtime calibration?

BTW: I have a QNAP NAS (FW 4.2.2) also connected via snmp to a APC Smart-UPS
1000 RM, that shows the same behavior that it shuts down after a given time
period when a runtime calibration is running...

Thanks for your help,
Oliver

Out of curiosity : Is there any difference between the output of command 
"upsc my-ups" during a runtime calibration and during a wall power 
failure?  Specifically, is there any difference between the ups.status 
values?

It occurs to me that you may not have seen Roger's response, since it does
not look like you were subscribed at that point.
