Login to OpsMgr via SSH

Create a directory e.g.

  mkdir 20160501_pcf_stop_start

Copy 01_download_deployment_manifest.sh, 02_create_stop_commands.sh and 03_create_start_commands.sh into the previously created directory.

Important: The commands will only be generated for jobs ins running state. Please make sure everything is running before executing using

  bosh vms | grep -v running

Run the following commands on the OpsMgr console (being logged via SSH)

  sh 01_download_deployment_manifest
  sh 02_create_stop_commands.sh > stop_commands
  sh 03_create_start_commands.sh > start_commands

Validate the content of the files stop_commands and start_commands. It is recommened that when executing you have two sessions open.

• Session 1: run the 'meta' commands in this session and keep *_commands open.
• Session 2: run the actual bosh commands here.
