All, It's hard to imagine that any customer is limited to specific volume size nowadays.
For a decade or so now all the storage vendors have delivered the ability to make right-sized volumes, usually only limited to what z/OS supported around the time the controller model was introduced. With virtual volumes now (HDS call it HDP) creating a right-sized volume is a piece of cake. Being in a lab this has made life extraordinarily easy to provision a range of volume sizes with a couple of mouse clicks, or some scripts. Alternatively, with thin provisioning offered by all three vendors you could make your SYSRES a 3390-54 and just use the space required for the one pack SYSRES. If you just use 20,000 CYLs then that's all you use from the pool - a bit like Iceberg revisited.

Once I've worked for a client that had 3-volumes respack. It indeed worked. We used to keep datasets like LINKLIB, MACLIB, NUCLEUS, etc in 1st volumes though... ------------------------------------------------------------------------------------------------------------------------------- *Lucas Rosalen* Emails: rosalen.lu...@gmail.com / *lrosa...@pl.ibm.com <lrosa...@br.ibm.com>* LinkedIn: http://br.linkedin.com/in/lrosalen Phone: +48 (71) 792 809 198 2016-04-21 10:45 GMT+02:00 Jake Anderson <justmainfra...@gmail.com>: > Hello, > > From the z/OS 2.1, I have started using Mod-27 as the Load > address(Respack) for IPLing the z/OS 2.1 LPAR.
