The focus of this document is providing a procedure for dynamically adding tape devices for MIA to manage using z/OS ACTIVATE.
Resynchronization is the MIA process which can dynamically change the devices defined to MIA for management. You can add tape devices for MIA to manage either by issuing the MIA RESYNCH command (for devices already genned) or by performing a z/OS ACTIVATE.
If you are adding existing tape devices (currently defined to z/OS) to MIA device management, then you will manually issue the MIA RESYNCH command. The MIA RESYNCH command is documented in the MIM Statement and Command Reference, so the complete description and use of the RESYNCH command will not be duplicated here. All MIM manuals are available for viewing online or for downloading as a PDF file.
If you will be performing a z/OS ACTIVATE to add tape devices, then MIA will detect the ACTIVATE and automatically perform a resynchronization. This resynchronization triggers the same internal process that occurs when an MIA RESYNCH command is processed. The rest of this document describes the process of setting up MIA for resynchronization prior to performing a z/OS ACTIVATE. A separate document will discuss using z/OS ACTIVATE to delete devices from MIA management.
Here is a summary of the steps when adding devices to MIA management using z/OS ACTIVATE:
