https://docs.dynatrace.com/docs/managed-cluster/operation/start-stop-restart-cluster

I am referring to this document.
Is the below process correct?

【Shut down cluster】
①Move to target directory:
"/opt/dynatrace-managed/launcher"

②Issue the following command on each existing node:
"sudo nohup ./server.sh stop"

③Issue the following command to check the status:
"sudo nohup ./server.sh status"

④When all server processes are fully shut down and a status check shows them as not running,
issue the following command on each existing node, one node at a time:
"sudo nohup ./dynatrace.sh stop"

⑤Issue the following command to check the status:
"./dynatrace.sh status"

【Start up cluster】
①Move to target directory:
"/opt/dynatrace-managed/launcher"

②Run on each node:
"sudo nohup ./firewall.sh start"

③Issue the following command on each existing node
"sudo nohup ./elasticsearch.sh start"

④Issue the following command to check the status:
"curl -X GET "localhost:9200/_cluster/health?wait_for_status=yellow&timeout=50s&pretty"

⑤Issue the following command on each existing node:
"sudo nohup ./cassandra.sh start"

⑥Issue the following command to check the status:
"sudo /opt/dynatrace-managed/utils/cassandra-nodetool.sh status"

⑦Issue the following command on each existing node:
"sudo nohup ./server.sh start"

⑧Once all server processes are up and running,
start the rest of the processes. Issue the following command on each existing node:
"sudo nohup ./dynatrace.sh start"

⑨Issue the following command to check the status:
"./dynatrace.sh status"

Hello,
Yes, the process sequence is correct if you have more than three cluster nodes.
If not, then you can invoke Dynatrace.sh file to stop start/restart the nodes om each server.
./dynatrace.sh start
./dynatrace.sh stop
./dynatrace.sh status

Cheers!
