If your data center allows expired CA VM:Backup tapes to be reused by an OS system, use this option to specify a tape data set security code to protect the tape data sets against unauthorized access by the OS system. Select PASSWORD, NOPSWD, or NOPWREAD in response to the following prompt on the Define Tape Handling screen:
Specify the type of OS data set protection on VM:Backup data sets:
CA VM:Backup tape data sets are password-protected against all access.
CA VM:Backup tape data sets are not password-protected against read or write access.
CA VM:Backup tape data sets are password-protected against write access only. Read access is permitted without a password.
This option is provided for other systems, such as z/OS, that honor tape password protection. CA VM:Backup ignores the tape data set security code because expiration dates protect its tapes.
Note: For more information about updating the VMBACKUP CONFIG file to configure this option, see the "TAPEPROT Record" section in the System Programmer Reference Guide.
