Glenn I think he wants to run wide on the migrates. So if he submits 10 migrates, he wants them to run concurrently. But the OP states it only mounts one tape and then all 10 requests are serialized to the one tape.
And if I understand his requirement - he is using HSM as an application backup process in-case of issues during the batch run. So like doing an Imagecopy before batch job runs, then restoring from the imagecopy after batch if there is an issue, is what I think he is trying to do. I would probably suggest increasing the number of BACKUP versions of the file since HSM does quite well at doing a backup when the data changes. What I do not know is the environment. How many tape drives does he have in his shop. How many can he allocate to DFSMShsm migration. What his overall need is for this type of process.

Even though it is single tasked, NOWAIT should just submit the request and then return control back so that the job is not waiting for the migration to complete.
