Willie, I was hoping someone would answer citing documentation. If they have, I haven't seen it.
Short answer is HSM mounts the last ML2 tape used to satisfy a HMIG / ML2 request. Since you have Duplex = Y for your migrate tapes HSM also wants to mount the alternate. Instruct your operators to reply N to the inevitable Can this tape be mounted msg. HSM will then migrate the dataset and initiate a Tapecopy of the ML2 tape when the migrate is done. Perhaps someone on the list can suggest a way to prevent the average user from migrating datasets to ML2? ________________________________________ From: IBM Mainframe Discussion List [ibm-m...@bama.ua.edu] On Behalf Of willie bunter [williebun...@yahoo.com] Sent: Tuesday, December 23, 2008 10:07 AM To: IBM-MAIN@bama.ua.edu Subject: DFHSM QUESTION - SETSYS PARTIALTAPE(MIGRATION(MARKFULL) BACKUP(MARKFULL)) Good Day To All, I have this parm coded in the DFHSM STC: SETSYS PARTIALTAPE(MIGRATION(MARKFULL) BACKUP(MARKFULL)) This partion has DUPLEX option: SETSYS DUPLEX(MIGRATION(Y) BACKUP(N) However, for some reason when a user issues a MIGRAT 2 command DFHSM issues a tape mount request for both copies. The problem is that one copy is offsite. Is there a reason why this is occurring?
