Using Global SHUTDOWN Commands to Stop CA MIM

When GTAF is running, we strongly recommend that you stop CA MIM on all systems rather than on a subset of the systems in your complex. Issue the CA MIM SHUTDOWN GLOBAL command. For example, issue this SHUTDOWN command from any system:

SHUTDOWN GLOBAL

Note: GLOBAL is the initial default value of the command. You can change the default value of the command to DUMP, FREE, LOCAL, or RESERVE with the SETOPTION SHUTDOWN command.

Note: For a description of the SHUTDOWN command, see the Statement and Command Reference Guide.

When GLOBAL is selected, CA MIM does not stop with an ABEND code or request an ABEND dump.

On z/OS systems in the MIMplex, GTAF takes offline any device that is not allocated on each local system. This ensures integrity of tape resources. After GTAF terminates, each managed tape device is left online to, at most, one system in the complex.
