Since we have dueling hypothesis, I decided to retest mine against my current level of software. With all my ML2 volumes Delvol'd to Markfull, I then issued a Migrate to ML2. Instead of the expected mount for an existing ML2, HSM mounted a scratch and added a ML2 tape. C'est le vie. We are currently at Z\os 1.9.
Willie, What level of Z\os are you running? At 1.4 the outsourcer I was working with at the time complained whenever someone issued a HMIG / ML2 because HSM issued mounts for an existing Primary/Alternate tapes. Of course the Alternate was off-site, hence the complaint. They had Partialtape Markfull as well. ________________________________________ From: IBM Mainframe Discussion List [[email protected]] On Behalf Of Douglas Shupe [[email protected]] Sent: Friday, December 26, 2008 12:17 AM To: [email protected] Subject: Re: DFHSM QUESTION - SETSYS PARTIALTAPE(MIGRATION(MARKFULL) BACKUP(MARKFULL)) Most likely you have sent a tape that has not been 'marked full' offsite. A list of your ML2 tapes should confirm this. You might consider checking the backup tapes also. ----- Original Message ----- From: "O'Brien, David W.
