Darth, >From what I see in the primary space management messages coming from DFHSM, the volumes these datasets are on do get processed by PSM. From the Storage Admin Guide, all the datasets on the volume are scanned for eligibility for being deleted. Pass 1 of PSM also deletes all datasets that are eligible based on MGMT class - regardless of whether they are backed up or not.
This is definitely puzzling to me. From what I can see, I have everything defined properly, but these things just won't go away.

The keyword here is ELIGIBLE. IIRC, deletion of datasets occurs during Primary Space Managment. PSM does not automatically occur for every volume in storage group. You have to know what your AutoMigration & threshold values are for the storage group and then look at how that works with the Thresholds defined for that storage group. This behavior is covered in DFHSM Storage Administration Guide. dd keller ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
