The CA VM:Tape Shared Disk facility allows multiple CA VM:Tape systems to share TMC and Audit files residing on CMS minidisks without using hardware reserve/release commands.
Shared CMS minidisk support is completely transparent to CA VM:Tape users. The VMTBKP program operates in a shared minidisk environment by using the SUSPEND and RESUME commands to prevent CA VM:Tape database access while VMTBKP is running.
Identical user IDs on multiple machines are considered to be the same user ID as far as the owner of the tape is concerned. If user ID OPERATOR creates a tape on CPU 1, then user ID OPERATOR on CPU 2 can perform any CA VM:Tape operation as the owner of the volume.
