Greetings, -Dave. From: The IBM z/VM
Operating System [mailto:[EMAIL PROTECTED] On Behalf Of William Boyer Last Friday we had a situation where
our production LPAR – running z/VM 5.1 with two z/OS guests – hung
or rather ran away with the CPUs. From the test LPAR, we only have two
LPARs, I could see using the Performance Toolkit that the production LPAR was
running at 97% + of all three CPU’s. The test LPAR, which only has one
CPU assigned to it was using the remaining percentage. When I tried to
logon to the production z/VM, I got no response until I got a message the
External Security Manager was unavailable. We run RACF/VM on the
system. Luckily, I had a userid logged on via the ICC however; when I
typed a command in I got an immediate NOT ACCEPTED. I then tried a PA1 to
get a CP READ that did work although it was slow. I was then able to
issue an We re-activated the LPAR and
everything came up normally. There was not trace of what happened in
dumps or anomalies in any logs either z/VM or z/OS. Anyone every have
something like this occur? If it occurs again does anyone have some ideas
of what to try to figure out what is happening? Thanks. William L. Boyer ViPSÒ, an
