There are many ways. Creating overflow groups generally get messy over time because of the nature of the allocations. There is also Extended Storage Groups that can be defined in the DFSMS Constructs. Again, this can become messy over time. Doing aggressive migration, whether through interval migration or lower thresholds of the storage groups can create serious thrashing problems within DFHSM. Creating the REXX based on IGD messages is an option. In order to perform the migration on the correct data sets to prevent problems, you will need to access the VTOC and determine based on days unreferenced, size, and data type what to migrate, and how many. Do you migrate everything based on 14 days unreferenced, greater than 300 cylinders, and only PS data sets, or do you pick some other criteria? Do you do something additional to move more data if the first migration did not create enough free space? Also using SAS and DCOLLECT is an option, which is what I used before I got gray hair. :-) I finally got tired of maintaining the code and bought a solution from a vendor. That was almost 15 years ago.

However, occasionally they do fill up and I need to manually do ML2 migrations so the appls can continue to work. I am considering creating a rexx that gets kicked off by OPS/MVS to do the migration for me. I would probably monitor for IGD17216I and IGD17272I. I was just wondering what other options might be available (other than interval migration in DFHSM). How do you handle the need to migrate datasets out of a pool when it gets too full. What type of automation or manual process to you have available to you.
