Halting the TSM Server

The HALT command forces an abrupt shutdown, which cancels all the administrative and client node sessions even if they are not completed. Any transactions in progress interrupted by the HALT command are rolled back when you restart the server.

Use the HALT command only after the administrative and client node sessions are completed or cancelled. To shut down the server without severely impacting administrative and client node sessions, perform the following steps:

1. Use the DISABLE SE command to prevent starting new client node sessions.
2. Use the QUERY SE command to identify any existing administrative and client node sessions.
3. Use the CANCEL SE command to cancel any existing administrative or client node sessions.
4. Use the Q PR command to identify active background processes.
5. Use the CANCEL PR command to cancel any active background processes.
6. Use the Q MO command to identify the status of any mounted tape volumes.
7. Use the DISMOUNT VOL command to dismount idle volumes.
8. With no existing administrative and client node sessions, no active background processes and no mounted volumes, run the HALT command to shut down the TSM server.
