CA MIA Activities During Local Shutdown

WARNING! When GTAF is running, we recommend that you stop CA MIM on all systems, rather than on a subset of systems in your complex. When CA MIM is stopped on one system, any new tape device activity on that system (such as allocations, z/OS VARY commands, or device name replies to IEF238D WTORs) will not be serialized with the rest of the systems in the complex where CA MIM is still running, creating data integrity exposures.

Tape resources held by the local system at the time CA MIM is stopped locally are not available for use by systems in the rest of the complex where CA MIM is still running until CA MIM is restarted on the local system, or the local system is freed through the CA MIM FREE command. A system can be automatically freed at time of shutdown by issuing the CA MIM SHUTDOWN FREE command.
