When I was with IBM Education, we used to run class labs on minimal z/OS (OS/390, MVS/...) systems as VM guests. The volumes were VM mini volumes just as large as needed. If VM is still the base for those labs, I'm pretty sure there still are volumes of various small sizes.
Not sure however if this matters for your query. --Peter Hunkeler -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of John Eells Sent: Tuesday, June 28, 2016 9:19 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Minimum Volume Sizes in the Wild What is the *smallest* volume size everyone sees in general use? For example, will we create any problems if we assume that "everyone" has or can define at least a 3390-9 size volume these days? What if we chose 3390-27? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
