Re: How Do I Eliminate ML2 Migration?
George, You actually need to make your datasets on DFSMShsm monitored volumes, or datasets in your management classes ineligible for ML2 migration. It's not about just simply turning it secondary space management - that won't work at all. The actual parameters that must be changed to do this will depend on whether you are SMS managed, or just running DFSMShsm against non-SMS volumes, or both. The information provided so far is simply to vague for anyone to answer. To answer one of your earlier questions, datasets eligible for ML2 will be migrated directly to ML2 during Primary Space Management. If you recall a dataset and do not change the last reference date, it will likely be migrated back to ML2 during the next Primary Space Management cycle - commonly known as thrashing. Secondary Space Management is looking for datasets on ML1 that have aged to become eligible for ML2. You need to do more than just stop secondary space management, and when you recall a dataset you need to change the last reference date so it does not migrate next primary space management cycle. An alternative to changing the last reference date would be to set up a management class that only goes to ML1, and assign all datasets to that management class when they are recalled. This is an environment you can test for in the ACS script. This will avoid the requirement to touch every dataset and change the last reference date. If you are not using DFSMS managed volumes you will need to create at least one Storage Group and assign STORCLAS to make this work. I don't think your simple exercise is really as simple as it sounds and you may want to spend a few days working through your ARCMMD and Management classes along with the reference guides and understand what parameters make a dataset a candidate for ML2 - because that's what needs to be changed. What about your DFSMShsm dataset and volume backups? Will you only be keeping local copies of those?

You need to plan. Your current setup uses tape for ML2. How much data is currently in ML2? How long do you keep it? How rapidly does it grow? You bought disk to replace the tape. How much disk? Is it enough to handle all the current ML2 data plus the anticipated growth? Do you want the data that is currently on ML2 tapes to remain in HSM or do you want them to end up on Primary volumes? If the datasets are to remain in HSM, you may not need to recall them at all. Once the SETSYS ML2 units are changed, either the RECYCLE or FREEVOL commands should move the data to DASD. If you want the datasets on primary volumes, you will need to recall them but you will also need to change other SETSYS options to prevent Secondary Space Management from putting data on new ML2 volumes. -Original Message- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@bama.ua.edu] On Behalf Of George Rodriguez Sent: Wednesday, March 16, 2011 11:55 AM To: IBM-MAIN@bama.ua.edu Subject: Re: How Do I Eliminate ML2 Migration? Barry, Are the parameter that I change these: SETSYS TAPEMIGRATION(ML2TAPE (TAPE(3490))) SETSYS MIGUNITNAME(3490) Does that mean that the migration still occurs, except it goes to disk? Does it also mean that I might need to increase the migration volumes to support migration? -- 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 Home of Florida's first LEED Gold Certified School Under Florida law, e-mail addresses are public records.
