Modifying parameters for the required settings

Log in to the PowerProtect Data Manager console as an admin user.
Edit the file /usr/local/brs/lib/sdmng/config/application.yml to modify the values for the required settings.
Restart the sdmng service using the sdmng restart command once the changes are saved in the application.yml file.

NOTE:Back up the application.yml file to another host in order to save your changes during the update process. Otherwise, the update process overwrites the file. Restore the configuration file post-update. Restart sdmng service using the sdmng restart command once the file changes are complete.
