The disk is defined as follows. This is an excerpt from the CP directory: IPL 200 ..... LINK RHMASTER 199 199 RR MDISK 200 3390 1 10016 LX53B5 M
Unfortunately, the console log did not get spooled so I don't know what the log would have indicated for that disk when the guest machine came up. That's on my follow-up list. The guest machine is IPL'd off of its OS (disk 200) disk when it comes up (in its CP Directory) so I need to find a way to spool the console when it starts and not later after it has gone through its initialization.

The mode will tell you the condition(s) that could lead to it being read only (other users having it read/write or even read only), and the log may even tell you which or how many users gummed up the works, or when things when oval on you. In any case, it had to have happened at some point, and there has to be a footprint, if you keep your logs. -- Robert P. Nix Mayo Foundation .~.
