You can download a FREE PDF of Bob DuCharme's book "The Operating System Handbook, or, Fake Your Way Through Minis and Mainframes". It is pretty basic but enough to get you started. Individual chapters or the entire book are available. For free I recommend the entire book. You may never need to know how to work with an IBM 360 or AS/400 but it is interesting to see how some of the available OSes compare, both to each other and to OpenVMS and UNIX.
I also found "OpenVMS System Management Guide" quite helpful. It covers more advanced stuff, a lot of it just not relevant for hobbyist use but there is enough in there to make it worthwhile if you can find an inexpensive used copy.
