How to deploy PowerChute Network Shutdown v4.3, v4.4 Appliance in vSAN cluster.

Published date: 16 October 2020

After deploying the PowerChute Network Shutdown Appliance to a vSAN Datastore, a configuration change is required to allow for graceful shutdown of the vSAN Cluster.

Product Line:
PowerChute Network Shutdown version v4.3, v4.4 

PowerChute Network Shutdown Appliance version v4.3, v4.4 deployed on vSAN Datastore on one of the Hosts that is part of the vSAN Cluster.

Software issue

  1. Log into the PowerChute Appliance as root
  2. Enter the command systemctl stop PowerChute to stop the PowerChute service
  3. Edit pcnsconfig.ini The command to enter is vi /opt/APC/PowerChute/group1/pcnsconfig.ini  If not familiar with using vi editor another option is to copy the file to a Windows system. Edit with text editor then copy the file back. 
  4. Add Skip_Maintenance_Mode = true to the [HostDetails] section of the pcnsconfig.ini file (see example below) and save the file. 
  5. Enter the command systemctl start PowerChute to start the PowerChute service
ConfigurationMode = Managed
Server =
Server_Protocol = https
Server_PORT = 443
nutanix_support = false
is_VCSA = true
Skip_Maintenance_Mode = true

When a UPS critical event  trigger PowerChute shutdown – all User VMs and Hosts are shut down gracefully.

The PowerChute VM gets powered off last when it’s Host is shut down.

NOTE: We will only support Single/Redundant UPS Configurations. For vSAN Stretched Cluster, PCNS needs to be deployed on the Management Host (runs the Witness Appliance outside the vSAN Cluster).
