Jesse, That's exactly the sort of testing we do. Truecopy, HUR, Flashcopy, Shadowimage, FCSE... Setting up target volumes on the primary, local and remote controllers is equally easy. Especially when we use scripts to provision tens of thousands of volumes in a single hit. The same script runs against each controller. Even using a GUI I can create 20,000 volumes with a mix of 10 cylinder. 3390-3/27/54/250/1GB sized volumes in about two hours starting with just the unformatted parity groups installed. I'm sure the other vendor's interfaces are equally fast and easy to use. Ron

We mirror all production DASD to our DR site. If I create an oddball volume in production, it requires creation of two more identical ones at the recovery site: one for direct mirroring and another one to flash to for running a system. This complicates volume mapping. I've been told by storage managers that 'wasted space' is a smaller problem for them than trying to manage odd-sized volumes. My few odd sizes are, for example, to contain sysplex couple data sets or JES2 checkpoint. Very small volumes for data sets that do not party well with others. . . .

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.
