Using environment variables to start and stop VCSMM modules
The start and stop environment variables for VCSMM define the default behavior to start the modules during system restart or stop the modules during system shutdown.
Note:
The startup and shutdown of VCSMM is inter-dependent on other stack modules such as LLT, GAB, fencing, and ODM. For a clean startup or shutdown of SF Oracle RAC, you must either enable or disable startup and shutdown for all these modules.
Table: Environment variables to start and stop VCSMM lists the environment variables to start and stop VCSMM.
