Perhaps 'z/OS system installation and maintenance', P.9, is sufficient: "The z/OS software- as supplied by IBM- is usually installed on a series of disk volumes known as the system residence volumes (SYSRES). Much of the flexibility of z/OS is built on these SYSRES sets. They make it possible to apply maintenance to a new set that is cloned from the production set while the current set is running production work. A short outage can then be taken to IPL from the new set--and the maintenance has been implemented! Also, the change can be backed out by IPLing from the old set."

How would you define the "SYSRES volume"? I want to give a good definition to new system programmers.
