IBM 3494 VTS - CBRUXEJC Volume Eject EXIT

The CBRUXEJC exit is invoked when a physical tape is ejected and when a virtual tape is exported. This exit will need to be modified if you are using the 3494 VTS with the import and export functions. A pseudo DSN will need to be defined so that CA TLMS can track the physical tapes used during the export, otherwise a default name will be generated. If you are using a 3494 VTS without the import/export feature, or if you are using a 3494 ATL, then no modification is needed to the CA TLMS supplied version.

During an export function, the following actions are taken on the virtual volumes being exported

• The ATLNUM field is set to zero
• The BOX/CCSS field is set to 'VTX'
• ACTUAL_VOLSER will be updated with the physical volser that the virtual volumes are being exported to
• The ASCTYP (Associated Type) field is set to 'V'

The following actions are taken on the physical volume (also known as the container volume)

• The ATLTYP field is set to VIBM
• The ATLNUM field is set to zero
• The ACTUAL_VOLSER and FSTVOL (First volume in chain) fields are set to the physical volser
• The ASCTYP (Associated Type) field is set to 'V'
• The DSN is set to the pseudo DSN defined in CBRUXEJC. If no DSN is defined in CBRUXEJC the following pseudo DSN will be used-"CATAPE.HOLDS.EXPORTED.VIRTUAL.TAPES.Vxxxxxx" where xxxxxx is replaced with the physical volser
• The KEEP DATE and EXPIRATION DATE is set to PERM
• The CREATING JOB is set to "OAM" and the CREATING PROGRAM is set to "TLMSQSTS"
• The VOLUME OWNER is set to 'VIBM'
• The LOCATION and RETURN LOCATION are set to the Data Center (DC)
• CREATION DATE and TIME are set to the current date and time

The pseudo DSN assigned to the physical volume should be added to the Retention Master File (RMF) to define your desired retention schedule for container volumes that consist of exported virtual volumes.
