So the original post was <snip> We've got a scenario where we should do a backup of some data to data sets and after succesful backup send the previous copy to ML2 (so we've got only the latest on DASD).
Since there are multiple backup jobs, we've tried to send a TSO command (via IKJEFT01 in the jobs) to HMIGRATE the old data sets, but as it turns out, HSM mounts only one tape per LPAR (if jobs are distributed to 2 LPARs => 2 parallel migrations). Since that's a bit slow, we're looking how to get some more instances running. </snip> And the OP has not responded back to us with any additional details on what problem is trying to be solved. I am guessing application backups, but it could be something else. The poster wants more than one process doing HSM migrates but HSM Serializes. There is no indication as to how many tapes (real or virtual) the poster has in the shop, the size of the tapes, or why this requirement is in place. Or what type of files this request covers, SEQ, GDGs, VSAM. I think he could do better with either more BACKUP versions of his datasets or use DFDSS or FDR to dump the files. Hopefully he will write back and provide some more detail.

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.
