deactivate some CPU

[Konrad Hegner]

Hi
We have planed some software-upgrade and this procedure needs some (3 or 4) reboots. We work with K380-machines and they have 6 CPU and 3GB RAM. And you know how long goes a reboot (CPU- and memory-check).
And we want to know now how I can disable 5 CPUs and the memory-checks. It is possible also to deactivate the CPU during the machine is running (of corse the change will be after the next reboot), but if we change this setings after the first reboot, we loos to much time and we have only a small timeslot for this upgrades.
I hope everybody understand my question.

Und hier in Deutsch: Fuer einen Upgrade muessen wir unsere K380 (6 CPU, 3GB RAM) mehrmals (3-4 mal)neu starten. Kann man 5 CPUs deaktivieren (Im bootmenu ist es bekannt)? Kann man diese 5 CPU waehrend des Betriebes deaktivieren, da wir ansonsten fast soviel Zeit verlieren, wie wenn wir die CPUs nicht deaktivieren?

Regards Konrad
