An IBM Virtual Tape server (subsequently called VTS) is a tape storage subsystem emulating virtual tape drives and virtual volumes. A Peer-to-Peer Complex (subsequently called PTP Complex or PTP) is an IBM storage subsystem which creates two copies of all virtual tapes in two (or more) Virtual Tape Servers, one copy of each volume on each VTS.. When a PTP is established pre-existing data is not automatically copied from one VTS to the other. This invention disclosure describes a method to initiate the copy of any or all volumes such that the VTS subsystems are synchronized automatically.
