Hi! 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. There has been a similar question by John McKown back in 2005, but as Steve pointed out in that thread, there are a few facts: - command recalls are single thread executions (per userid?) - MAXMIGRATETASKS is only effective for primary space management I've tried to submit 2 jobs running under different users on the same LPAR and it's still single threaded.. Any ideas or experiences with similar problems? Thanks..
