Setting Up an Automated Tape Environment With the Tape Library Data Server

The 3494 and 3495 Tape Library Data Servers require the RMS component of DFSMS/VM Function Level 221.

To set up the RMS interface to CA VM:Tape, follow these steps:

1. End CA VM:Tape.
2. Edit the VMTAPE CONFIG file:
   1. Add a PRODUCT RMS record to define the RMS interface.

      The PRODUCT RMS record, shown below, defines the Tape Library Data Server interface to CA VM:Tape. For more information about the PRODUCT record, see the PRODUCT Record.

      PRODUCT RMS
      

   2. Add or modify the DEVICE record to include tape drives that are both inside and outside the Tape Library Data Server. The DEVICE record identifies tape drives CA VM:Tape will manage, including those both inside and outside the Tape Library Data Server.

      To identify any RMS devices, add or modify the DEVICE record in the VMTAPE CONFIG file as follows, replacing devices with the list of RMS devices:

      DEVICE devices
      

      Use the NAME parameter on the DEVICE record to group tape drives. You can then direct tape mounts to a specific set of drives by specifying the group name using the NAME parameter on the MOUNT command. You can also use the LOCATION option on the MOUNT command to direct mounts to specific Tape Library Data Server locations.

      For more information about the DEVICE record, see the DEVICE Record.

   3. You can optionally add one or more RMSRANGE records to indicate specific ranges of tapes for CA VM:Tape to consider belonging to a specific RMS location:

      RMSRANGE start_vol-end_vol location
      

      Note: If you implement RMSRANGE config file records, synchronization with the IBM 3494 robot is bypassed during CA VM:Tape REFRESH processing.

      For more information about the RMSRANGE record, see the RMSRANGE Record.

   4. You can optionally add an RMSSCRCT record to specify a list of scratch categories that CA VM:Tape can use. For more information see RMSSCRCT Record.
3. Save and exit the VMTAPE CONFIG file.
4. Add the CA VM:Tape service virtual machine userid to the DGTVAUTH DATA file in DFSMS/VM to authorize CA VM:Tape.
5. Ensure that the Tape Library Data Server name specified on each RM_AUTO_LIBRARY keyword in the DFSMS/VM control file, DGTVCNTL DATA, is no longer than eight characters. (While DFSMS/VM allows up to 32 characters, CA VM:Tape uses eight-character names.) For more information about the DFSMS/VM control file, see the appropriate IBM DFSMS/VM installation and customization manual.
6. Ensure that the CA VM:Tape service virtual machine has access to the RMS support minidisk or directory. The CA VM:Tape service virtual machine requires access to the FSMPPSI CSLLIB for RMS support. Access this disk or directory in the server’s PROFILE EXEC.
7. Before you initialize CA VM:Tape, ensure that the volsers that are already inside the Tape Library Data Server are defined in the CA VM:Tape TMC. For instructions on adding the volsers and adding or removing volser series in the VMTBUILD utility, see VMTBUILD Utility.

   When all volsers inside the Tape Library Data Server are already defined in the CA VM:Tape TMC, you can continue to the next step.

8. Restart CA VM:Tape.
9. Use the CA VM:Tape RMS command with the START parameter to initialize the RMS interface, synchronizing the locations of the tapes in the Tape Library Data Server with the CA VM:Tape TMC:

   vmtape rms start
   

   Because CA VM:Tape is defining the tape locations in the Tape Library Data Server for the first time, this step will take a few minutes to complete. Adding the tape locations causes CA VM:Tape to rebuild the picklist to add the new locations.

   Note: For more information about the RMS command, see the Command Reference Guide.

10. You can use the CA VM:Tape SET LOCATION command to make the Tape Library Data Server the default location for all scratch tape mount and allocate requests. If the Tape Library Data Server location is not available, CA VM:Tape uses tape drives outside the Tape Library Data Server -the NONARM drives.

    For example, to specify the Tape Library Data Server location IBMARM01 as the default location, enter:

    vmtape set location ibmarm01
    

    Note: For more information about the SET command, see the Command Reference Guide.

11. You can now use the Tape Library Data Server with CA VM:Tape.
