Disable health broker service ( vrhb-service ) on vRA 7.x
Perform the following steps to ensure that vhrb service is disabled and not monitored by cron jobs
Note: Take Snapshots ( No Memory, No Quiescing )
Stop the health service monitor by commenting out the cron job in /etc/cron.d/monitor-vrhb-cron

Kill any instances of monitor that might be running by executing
ps -A | grep monitor-vrhb.sh | awk '{print $1}' | xargs --no-run-if-empty kill -9 $1

Stop the health service by executing the command
service vrhb-service stop

Verify if the service is stopped if a process is found kill it manually
ps aux | grep Quorum

Cleanup the Health Service datastores ( aka Sandboxes )
rm -r /var/lib/vrhb/service-host/sandbox
rm -r /var/lib/vrhb/vra-tests-host/sandbox

Note : I have not configured health broker service in my lab so you would not see vra-test-host/sandbox command being executed
As a last step, turn off vrhb-service using chkconfig
chkconfig vrhb-service off
