You may want to use the OS Simulation Standard Label Tape Processing Exit (DMSTVI) to allow CMS OS Simulation support to interface with CA VM:Tape. DMSTVI supersedes the VM tape volume switching exit (also known as DMSTVS). DMSTVS remains available and can be used if you place it on a disk accessible to those who require it.
Note: For more information about using OS Simulation with DMSTVI and DMSTVS, see the Command Reference Guide. For more information about DMSTVS, see the CMS Command Reference and User’s Guide appropriate for your system.
CA VM:Tape provides a module, VMTTVI, which will generate the DMSTVI exit for your use. During installation, the VMTTVI MODULE is loaded to the VMANAGER PUBLIC disk, usually the VMANAGER 193 minidisk. If, after the installation is complete, DMSTVI MODULE does not exist, generate the exit manually by entering the VMTTVI INSTALL command:
vmttvi install vmtape
In this example, vmtape is the name of your CA VM:Tape service virtual machine. CA VM:Tape creates the DMSTVI module on your A-disk.
Copy DMSTVI MODULE to a public minidisk to make it available to all users. Keep the original VMTTVI MODULE in case you need to regenerate DMSTVI at some future time.
