Improper AMM shut down can cause adverse effects on the system, such as database corruption.
From AMM 2.17.3, the proper procedure to shut down an AMM is as follows.
For earlier versions of the AMM, the proper procedure to shut down an AMM is as follows.
1. Become user root either by logging in on the console as root, or by logging in as user imtadmin and executing su - .
2. To stop the AMM processes, type ammctl stop
The on-screen output will show information about AMM processes being stopped. If high availability is detected, it may ask the user to shutdown HA manually. This should be ignored.
3. To stop the database processes, type systemctl stop mysql
4. Type sync
5. Type echo 1 > /proc/sys/vm/drop_caches
6. Type systemctl reboot
