Chris raises a great point. You really should keep your z/OS doc on Windows - you're never going to need it more than when z/OS is down.
How funny! Using this "reasoning", I should put all of my z/OS doc on Windows and all of my Windows doc on z/OS. That way if either is down I can use the other to read the doc (and hopefully get it back up). Do you /really/ put your Windows doc on z/OS??
My Linux doc resides on Linux. My Windows doc resides on Windows. My Mac OSX doc resides on Mac OSX. My OS/2 doc resides on OS/2. And -- believe it or not -- my z/OS doc resides on z/OS. I consider the practice of putting doc on an alternate platform to be inconvenient. And, in the case of z/OS, I want to retain the option of reading the doc directly from a TSO/E session.
What do I do when my Windows desktop fails and I need to read the doc to (for example) remember how to reboot into "Safe Mode"? I simply read the doc from my laptop, also running Windows. And what do I do when (God forbid) one of my z/OS images fails and I need to read the doc to (for example) interpret a wait-state code or take a stand-alone dump? I simply access the doc, either directly or through the Library Server for z/OS web interface, via one of my *other* z/OS images in the same parallel sysplex. After all, I'm allowed to have more than one. Unplanned outages are precisely why we have concepts like sysplex-enabled VIPA fail-over in the first place! Sheesh!
In our shop, more and more function is moving TO the mainframe -- not the other way around. First we established our primary DNS there. Subsequently, we set up our autoresponders there for certain customer-initiated web-based requests (like grace codes, product downloads, etc.) Last year, we moved our primary internal file server there (using DFS/SMB server). Most recently, we put our problem tracking data base there (with software running on Linux under z/VM). The results so far have been excellent. More is planned...
