Nutanix AHV: Default User VM Shutdown Duration is used instead of the configured duration in an Advanced UPS configuration in PowerChute Network Shutdown

In an Advanced UPS configuration, when a critical UPS event occurs on a Physical UPS setup (one that has no AHV host associated), the default User VM (UVM) shutdown duration of 120 seconds is used instead of the user-configured duration.
PowerChute Network Shutdown v4.3

PowerChute v4.3 configured with Nutanix Acropolis Hypervisor (AHV) support and Advanced UPS configuration.


Follow the steps below to edit the pcnsconfig.ini file to update the UVM shutdown duration for the unmapped UPS group:
  1. Open pcnsconfig.ini using an ASCII text editor, e.g. Notepad++.
  2. Navigate to the [advanced_ups_setup_X] section in the ini file – for the physical UPS setup. This is the UPS setup that has no hosts associated, i.e. hostlist key is not present under [advanced_ups_setup_X].
  3. Add a new key “uvm_shutdown_duration“ and set the value to the required duration, e.g. uvm_shutdown_duration = 300.
  4. Save and close the ini file.
