My guess is that you can install on models larger than model 9, but you will need the same number of volumes as for an installation on model 9.
This idea/guess is confirmed by the second sentence that you read. It is however possible that the allocation for page and spool would only cover the model 9 area. If you want you can change them to fullpack manually after the installation. A CP Q ALLOC MAP -executed after installation- will tell you how the allocation is. If they go higher than 10016, they will probably be fullpack. So, remember: verify at the end, and assure the defintions of the dummy $PAGE$ and $SPOOL$ users in the CP directory match with what Q ALLOC MAP says. 2011/2/9 Jakub x <jszef...@gmail.com> > Hello, > Can I install z/VM (5.4 or 6.1) on dasd 9 model 27 ? > > I found in documentation "Only 3390 Model 3 or 9 is supported for > installation of z/VM.
