What are the steps to shut down / boot the entire system in an Azure Stack HCI configuration?

Question

Q1: The shutdown and startup procedures assume the following, but is this understanding correct?
What we would like to confirm is "Procedures for safely and automatically shutting down the entire system in an emergency such as a power outage". And "Procedure to automatically start the entire system when power is restored".

Stop

1. Shut down all virtual machines
2. Node resume
3. Cluster stop
4. Host stop (servers that constitute s2d)
5. Host stop (quorum monitoring server)

Start

1. Host startup (quorum monitoring server)
2. Host startup (quorum monitoring server)
3. Cluster start
4. Node resume
5. Start virtual machine

Q2: What is the meaning of "2. Node resume" at the time of stop in the above assumed procedure?
Please teach me about the need for this procedure.

Q3: The following your document states "Pause the servers participating in the cluster, drain them, and then stop the servers".
https://learn.microsoft.com/ja-jp/windows-server/storage/storage-spaces/maintain-servers
We understand that "how to shut down each server participating in a cluster". Is this correct?
(We understand that it's not a system-wide shutdown with an Azure Stack HCI configuration)

Thank you.

o Make sure there is no Storage Job running on any node by running "Get-StorageJob" Command. If there is any job running, wait for the job to complete.
o Shutdown all VMs on the cluster
o Take the virtual disks offline.
o Take the Cluster Shared Volumes offline under ‘Storage ---> Disks’
o Take the Storage Pool offline from FCM.
o Stop the cluster "Stop-Cluster -Cluster <Cluster Name> " Or use Failover Cluster Manager to stop the cluster.
o Disable the cluster service on each node.
o Set Cluster Service to Disabled in services.msc
o Shutdown\Restart the node.

o Set the cluster service back to Automatic on each node in services.msc
o Start the cluster.Run "Start-Cluster -Name <ClusterName>"
o Bring the Cluster Pool back online.
o Use Failover Cluster Manager to bring the Cluster Pool online under ‘Storage ---> Pools’
o Bring the virtual disks back online.
o Use Failover Cluster Manager to bring the Cluster Shared Volumes online under ‘Storage ---> Disks’
o Monitor the status of the virtual disks by running the Get-Volume and Get-VirtualDisk cmdlets.
o Check if there is any Storage Job kicked off by running "Get-StorageJob" and let it complete.
