Suspended mode temporarily disables the ability of the primary companion to fail over to the secondary companion. When you move companions to suspended mode, synchronization between the companions does not occur, and the primary companion cannot fail over to the secondary companion. However, suspended mode is useful for performing such maintenance tasks as changing configuration parameters. To switch from normal companion mode to suspended mode:
As “root”, issue cmhaltserv to disable the monitoring process so it does not trigger a fail over when you shut down the companion server, where primary_package_name is the name of the primary package, which is also the same as the name of the primary companion:
cmhaltserv -v primary_package_name
Move the companions from normal companion mode to suspended mode. Issue the following from the secondary companion:
sp_companion primary_server_name, suspend
You can now shut down the primary companion as necessary and it does not fail over to the secondary companion.
