Install an SMS Managed IBM Tape Library

If you do not have an IBM Automated Tape Library (ATL) or Virtual Tape Server (VTS), skip this section.

CA 1 provides full support for the SMS managed tape libraries IBM ATL and VTS systems.

CA 1 support includes the ROBSCR option that notifies the IBM ATL or VTS when a tape is scratched. The ROBSCR option is in hlq.CTAPOPTN(TMOOPT00). This option requires you to use the CA 1 provided sample exits CBRUXENT, CBRUXEJC, and CBRUXVNL.

The CTSSYNC synchronization utility is also provided.

If you have installed the CA 1 version of CBRUXENT, CBRUXEJC, or CBRUXVNL, CA 1 should be active before starting OAM.

CA 1 scratch subpooling is not supported in the IBM ATL and VTS Tape Library Data Server.

Note: For information about the IBM ATL and VTS Tape Library Data Server support, see the Administration Guide.

Two methods are provided to install support for the IBM ATL and VTS.

If you want to use the DFSMS SMP/E zone only, do the following:

Follow these steps:

  1. Modify the source that the SMPPTFIN in CTSJUCBX references.
  2. Submit hlq.CTAPJCL (CTSJUCBX) to receive and apply the usermod your DFSMS SMP/E zone.
  3. Verify that the CA 1 option ROBSCR is set to YES in hlq.CTAPOPTN member TMOOPTxx.
  4. Verify that the ROBTY field is updated accordingly. If the field is set properly, the option ROBSCR is unable to notify the ATL that the tape is scratch. To update the ROBTY field properly, verify that modifications were made to CTSUXENT’s ATLTABLE label as part of the CA 1 usermod cai.CTAPJCL(CTSJUCBR) done in step 1. If there are current tapes in the robot with the current ROBTY field blank, it is required to update the appropriate ROBTY in ISPF or TMSUPDTE before setting ROBSCR=YES.

If you want to use the CA 1 SMP/E zone and the DFSMS SMP/E zone, do the following:

Follow these steps:

  1. Modify the source that the SMPPTFIN in CTSJUCBR references.
  2. Submit hlq.CTAPJCL (CTSJUCBN) to receive and apply the usermod to your CA 1 SMP/E zone. This way you assemble and link CTSUXENT, CTSUXEJC, and CTSUXVNL as CBRUXENT, CBRUXEJC, and CBRUXVNL in your hlq.CTAPJCL.
  3. Submit usermod hlq.CTAPJCL (CTSJUCBR) to receive and apply the usermod to your DFSMS SMP/E zone. This usermod renames your existing CTSUXENT, CTSUXEJC, and CTSUXVNL in SYS1.LINKLIB. You can optionally change the TONAME field that the SMPPTFIN in CTSJUCBR references to a name of your choosing.
  4. Verify that the CA 1 option ROBSCR is set to YES in hlq.CTAPOPTN member TMOOPTxx.
  5. Verify that the ROBTY field is updated accordingly. If the field is not set properly, the option ROBSCR is unable to notify the ATL that the tape is scratch. To update the ROBTY field properly, verify that modifications were made to CTSUXENT's ATLTABLE label as part of the CA 1 usermod hlq.CTAPJCL(CTSJUCBN) done in step 1. If there are current tapes in the robot with the current ROBTY field blank, update the appropriate ROBTY in ISPF or TMSUPDTE before setting ROBSCR=YES.
