NMC + PCNS + two hosts
This was originally posted on APC forums on 7/17/2019
Hello everybody, I'm Grzegorz, it is my first post.
I bought UPS Network Management Card and installed on my UPS (Smart-UPS 2200). I connected two server with using PCNS. First server with Hyper-V and second server with Linux. Hyper-V host is Main group and Linux host is Group 1. PCNS configuration on Hyper-V - only Virtualization Settings with VM shutdown on delay 300 seconds, PCNS configuration on Linux is clear, default. NMC calculate Power off delay on Main group 120 seconds and on Group 1 420 seconds - it's clear I understand. I change on NMS shutdown options Low Battery Duration - 30 minutes, NMS calculate Maximum Required Delay is 2 minutes - why two minutes not seven ? After lost power, ups is on battery power and waiting, waiting and Low Battery Duration on - first shutdown Linux after 120 seconds - ok. In the same time shutdown Hyper-v host (first VM) but when Linux is off on UPS- Status-Runtime Remaining time is not <30 minutes only >30. Is any way to stop shutdown Hyper-V host and wait with shutdown again when Runtime Remaining is again <30 minutes?
