Protecting Access to Tape Volumes

You can protect access to tape volumes through CA ACF2 for VM validation and system operator procedures. To access a tape volume:

1. Enter the ACFMOUNT command specifying the volume serial number of the tape. You can enter the virtual device address of the tape drive where the tape will be mounted and the type of operation performed (read or write).
2. If you implement command limiting for the ACFMOUNT command, the ACFMOUNT command limiting rule is validated to see if you have the authority to issue the command. ACFMOUNT command limiting is not required to implement CA ACF2 for VM tape volume access validation. ACFMOUNT command limiting enhances auditing.
3. CA ACF2 for VM performs ACFMOUNT command validation that is not related to command limiting.
4. A tape volume access rule is validated to see if you can read from or write to the specified tape volume.
5. If access is allowed, CA ACF2 for VM prompts the system operator to mount the indicated volume.
