Issue:
When PowerChute Network Shutdown commands a Nutanix cluster to shut down, the cluster does not shut down as expected.
Product:
PowerChute Network Shutdown 5.x
Environment:
Nutanix AOS 7.3 and above with AHV and ESXi
Cause:
Starting with AOS 7.3, the terminal multiplexer (TMUX) is enabled by default when an SSH session is initiated. This prevents PowerChute from successfully sending the cluster stop command.
Solution:
Disable TMUX. Refer to the Nutanix Knowledge Base article for instructions on disabling TMUX.
