Hi NN,

Assuming you want to put slave services in Maintenance Mode in Ambari before you stopping the services

Go to the service -> service Actions -> Turn on Maintenance Mode.

Please refer the below screen shot:

Hi @subhash parise,

Thank you! No alerts were observed after the maintenance mode was enabled.
