Verifying CA Vtape is Operational

Multiple CA Vtape console commands will be referenced in this section to display various installation related items. These commands are documented in mixed case where the uppercase characters are those characters that must be entered for the Subsystem to identify the command.

Note: For complete descriptions of the commands and sample output, see the chapter “Console Commands” in the Administration Guide. If you detect problems during the verification steps, see the chapter “Troubleshooting” in the Administration Guide.

1. Issue the SVT1 Display Status console command to display the status of the Subsystem or started task. Check the following items:
   • Version is correct.
   • DSN prefix is correct.
   • Virtual Volume Size is correct.
2. Issue the SVT1 Display Parmlib console command. Check the following items:
   • ParmlibDirectory, SystemOptions, GroupDefinitions, VirtualDeviceList, and DatasetFilters. Are they set to the correct parmlib member names?
   • Is an include filter coded?
3. Issue the SVT1 Display POOLS console command to display the defined pools and VOLSER ranges.
4. Submit a job using a data set name or data class that matches your test filter and use a UNIT parameter value that contains the Virtual Devices.

   The mount request should be intercepted and written to a Virtual Volume.

5. Submit a job to read the Virtual Volume and verify its content.
6. Display the Virtual Volume in the CA Vtape ISPF Interface.

   Edit HLQ.CCUUEXEC(SVTSMON) and complete the customization comments. Execute the customized SVTSMON member to start the CA Vtape ISPF Interface.

   Select option 3 to view the virtual VOLSER ranges. Select the range containing the Virtual Volume written. Select the actual Virtual Volume and review the data set name, DCB statistics, and other information. Compare this information with the information contained in the Tape Management System.

   In the top center of the display is a field named Flags. This is a four byte field displayed in hexadecimal. The bits that make up this field document the status of the Virtual Volume. How to interpret this field and much more about the ISPF Interface is documented in the chapter “ISPF Interface” in the Administration Guide.

Product verification is complete. You were able to intercept a tape mount, read, and write to a Virtual Volume.

You were introduced to the ISPF Interface and various console commands that you may need to use in the future. Reading about these and the other console commands is highly recommended.

There is one last console command that you should issue, SVT1 HELP. This console command lists the syntax of all CA Vtape console commands. Until you are familiar with the console commands or when you cannot find a copy of the Administration Guide, you can use this command to find the console command you are looking for and its syntax.

If you are doing a trial installation, at this point you have installed and configured CA Vtape successfully to perform the trial. The following chapters of this manual document jobs you should run for a production implementation and present additional topics concerning changes to the basic, recommended configuration that might be more appropriate for your environment.
