Graceful shutdown for Viptela appliances?

[helloguys]

Viptela appliances(vManage, vSmart, vBond, vEdge) are built on Linux platform.  What command do we use to do graceful shutdown?  I searched Cisco docs but couldn't find the command.  "shutdown" command is not available in vshell.  Thank you!

You should not do this from the appliance management CLI, but rather from your hypervisor. E.g. to shutdown controllers or vEdge gracefully on ESXi, you should select "Power -> Shut Down Guest OS" and you will see on the console:

It's like when you short-press your power button on your PC with ACPI. It will send signal to gracefully shutdown (as opposed to long press that will lead to loss of power and hard stop)

I tried poweroff command, it worked!

vManage# po?
Possible completions:
poweroff Shut down the system
vManage# poweroff
Are you sure you want to power off the system? [yes,NO] yes
wall: cannot get tty name: Success

Broadcast message from root@vManage (somewhere) (Tue Mar 8 19:54:34 2022):

Tue Mar 8 19:54:34 UTC 2022: The system is going down for poweroff NOW!

Yes, for a graceful shutdown, it is recommended to use 'poweroff'
You can check the LEDs on the device.
SYS will be solid red when the box is powered off. [screenshot enclosed]
