Use the following guidelines when you start or stop the Data Vault Service components:
Only one Data Vault Service can be running in the server cluster at any time. The Data Vault Service on the primary server and the Data Vault Service on the failover server cannot be running at the same time. If a Data Vault Service is running, you must shut it down before you start another Data Vault Service.
On the failover server, you cannot run the Data Vault Service and the Data Vault Service agent at the same time. You must stop the Data Vault Service before you start the Data Vault Service agent. If the Data Vault Service agent is running, you must shut down the agent before you start the Data Vault Service.
