Automated Graceful shutdown in case of power outage

specs : vSphere 6.7 HP R5000 UPS

I am looking for a way to shutdown in a certain sequence not just mass shutdown

example vm1, vm2, vm3 and last your DC, then host, UPD etc

I have read a lot of the option, posted online .. wondering if anyone here in the community

might have a better option. Step by Step

one of the option Scripts I have found

freenasid=`vim-cmd vmsvc/getallvms | sed '1d' | awk '/Eds-FS.vmx/{print$1}'`

vmids=`vim-cmd vmsvc/getallvms | sed '1d' | awk '{print$1}'`

for vmid in $vmids

if [ $vmid != $freenasid ]

then

powerstate=`vim-cmd vmsvc/power.getstate $vmid | sed '1d'`

if [ "$powerstate" = "Powered on" ]

then

onvmids="$onvmids $vmid"

done

for vmid in $onvmids

vim-cmd vmsvc/power.shutdown $vmid

done

exit 0

I have heard it works, but does not solve the problem - I am looking for an answer to

the script is free for all, as the developer gave it out free to all and myself.

if someone has some experience in this that would be great

thanks in advance.
