Our operators attach and detach real devices, almost always tape drives, sometimes OSA ports, to our guests. It is nice to be able to have them enter commands in the odd situations that pop up from time to time, particularly when the system programming staff is not near a terminal, or the system hangs (we always seem to find weird deadlocks within VM, or get bit by the "minidisk cache ate our page frames" bug). We encounter a problem and take a SNAPDUMP about once a year or so. I guess the bottom line is that its nice to have a manned local operator console when severe problems strike.

So, my RACF question and all the answers y'all gave made me think of another... What do your operators do within z/VM? The reason I ask is because we haven't given our operations staff access to any of our z/VMs. What am I missing? Why do they need access? What should they be doing and aren't? (Mind you, we are zLinux only.) Leland
