The instructions for shutting down a cluster are to use “sudo shutdown -P now” on the CVM’s in the cluster to shut each one down, but the command only works on the first CVM. The command errors out the rest of the CVMs because they can’t reach the first CVM that was shut down. Am I missing something?

I have done this dozen of times. Only the first CVM shutdown down with that command. The other CVMs won’t shut down because they can’t reach the first CVM that is shut down.
Is it Esxi or AHV?

@TimothyGray Can you post the error you are seeing here?
When you run this command on the first CVM, the first CVM will successfully grab the shutdown token (since none of the other CVMs are currently holding this token as all CVMs are UP) and then power down the CVM. However, when you try to run the same command again on other CVMs when the first CVM is already down, the first CVM won't release the shutdown token while it is offline and so the above two commands won’t work in this case as you observed for your cluster as well.
Since your end goal is to shut down multiple CVMs on the cluster at the same time, hence in this case, the standard Linux shutdown command must be used on each CVM to power it down:
The above linux command won’t check for any shutdown tokens and so multiple CVMs can be taken down at the same time.
An important point to note here is that this command should only be used on CVMs when the cluster is in stopped state (user VMs are powered down already) and you want to shutdown multiple CVMs at the same time. For any other case, always use “cvm_shutdown -P now” command to shutdown the CVM.
Kindly let us know if the above command helped to resolve your issue.
