Manually migrating virtual tapes
You can migrate a pool, which migrates all virtual tapes in the pool, or a single virtual tape.
The virtual tape or pool is migrated according to the hsm_ parameters in the VTS
configuration file.
Requires the HSM Migration access right

Automating migration using VTSPolicy
After enterprise integration is configured, you can use VTSPolicy to initiate migration by
having the NonStop server send an EMS message to the VTS server. The VTS server then
passes the command to the BMA. VTS waits for the return code from the BMA. If a successful
return code is received, VTS marks the virtual tape as migrated to physical tape. If the return
code indicates a failure, VTS does not mark the virtual tape as migrated and notes this in the
log file.
If the NonStop server requests a virtual tape that was migrated, VTS checks the size of the
requested virtual tape. If the size is 0, the virtual tape was erased and VTS attempts to
retrieve the data and recreate the virtual tape from physical tape. To accomplish this, VTS
