Initializing CMS and reading TESTNUC MAP places the nucleus load map
on the test userid's CMS A-disk. By saving the load map on this disk,
the test system at the virtual CP level can use IPCS to access it and
create problem reports.

recognized by the virtual V8/370 system. Notice that the 330 disk has
read/write status (this is required for VM/370 to do virtual paging and
sFcoling). All the other disks have read-only status. Disks 191 and 290 are not recognized by the virtual VM/370 system because they are not

This outFut is from the V8/370 system running in a virtual machine.
It is printing the responses on what appears to it as a virtual 3215
console. Note that the CHANGE TOD CLOCK (YES/NO) prompting message does
not require a response. If the response had been yes, it would have
requested a date and time to be set; however, the real time-of-day clock
cannot be changed from a virtual machine environment. The LINK error
messages are a result of the automatic operator logon and of the
directory net being able to find some disks defined in the operator's
virtual machine. The "RING" message is the real CP simulation of the
virtual console alarm function. Finally, the operator receives
confirmation of a logon.
