>>Hi Listers, >>We would like to reduce the tape utilisation of HSM by adding more DASD for >>migration.
>>The question is whether to add more as ML1 or add some as ML2. ..... >>Alternatively, is there a way to force these direct Primary to ML2 >>migrations to be directed to ML1 instead of ML2? >>>>>>>>>>>>> Can't say I've ever heard of someone mixing DASD & Tape for ML2 nor of anyone ever using DASD as ML2 - I guess I'd have to ask why you'd want to? Why have 2 different levels of migration on DASD? Why not just increase the amount of Level 1? As far as you 2nd question about directing Primary to ML2 migrations to go to ML1 instead of ML2 - If you're an SMS shop, you need to look at your management class definitions as your "PRIMARY DAYS" & "LEVEL 1 DAYS" parameters are what controls which datasets migrate to ML1 and which migrate to ML2. As an aside, I just recently went the other way and changed my parameters so that more of my datasets migrated directly to ML2 rather than ML1 - we had larger #'s of datasets which sat around on ML1 without ever being recalled and then being migrated a 2nd time to ML2. Plus as a user of virtual tapes, the recalls from virtual tape are not that big an impact to our shop. dd keller ************************************************************************************** This e-mail message and all attachments transmitted with it may contain legally privileged and/or confidential information intended solely for the use of the addressee(s).
