AIVS processing provides an effective way to track tapes created on a non-CA 1 system. With AIVS processing, CA 1 can track foreign and duplicate volumes. Foreign volumes are those volumes created outside of the control of CA 1, while duplicate volumes are those volumes with volume serial numbers which conflict with volumes defined to CA 1. Duplicate volumes are typically volumes which have been created on another CA 1 system whose TMC is being merged with an existing TMC.
AIVS support is provided in CA 1 by recording the internal or actual volume serial number (ACTVOL) from the tape header in the TMC and tracking the tape with an external volume serial number defined to CA 1. When an AIVS tape is to be opened for input processing, the JCL VOL=SER= parameter or system catalog entry for the file must refer to the external volume serial number. The mount message issued contains both the external and actual volume serial number obtained from the TMC volume record.
AIVS tapes are defined to CA 1 either by directly entering the foreign tape information through the Build New TMC Record online command or by executing the TMSMERGE utility to merge another TMC with duplicate volume serial numbers. If an AIVS tape is to be reused, it must be initialized with an actual volume serial number equal to the external volume serial number.
