1 CPU Failed

[Andrew Merritt_2]

There should be an event logged in /var/opt/resmon/log/event.log if the diags are disabling the CPU, so take a look there.

What version number does STM show when you run it?

Regarding the STM CPU info tool, on 11.23 the CPU information is shown by the 'system' info tool, there is no separate CPU Info tool (which was the case on 11.11), so you need to do:

echo "selclass qualifier system;info;wait;infolog" | cstm
