The focus of this document is providing a procedure for dynamically deleting tape devices that MIA manages using z/OS ACTIVATE.
Resynchronization is the MIA process by which you can dynamically change the devices defined to MIA for management. To dynamically remove devices from MIA device management, you can trigger the MIA resynchronization process in 1 of 2 ways - by issuing the MIA RESYNCH command or by performing a deleting z/OS ACTIVATE. The MIA internal process is the same for both of these.
If you are removing tape devices from MIA device management without doing a z/OS ACTIVATE, then you will manually issue the MIA RESYNCH command. The MIA RESYNCH command is documented in the MIM Statement and Command Reference, so the description and use of this 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 delete tape devices, then MIA will detect the ACTIVATE and automatically perform a resynchronization. The rest of this document describes the process of setting up MIA prior to performing a deleting z/OS ACTIVATE. Here is a summary of the steps:
- CURRENT RESYNCH OPTIONS: DEVCLASS=NONE DEVLIST=MIAUNITS COMMANDS=NONE SAMEDEVS=NOThe RESYNCH options will be used by MIA when either manual (RESYNCH command) or an automatic (z/OS ACTIVATE) resynchronization occurs. To briefly describe the RESYNCH options:
