I am running into a licensing issue with one of my sofwtare suppliers.
How do I disable one core on a cpu
My map looks like this:
CPU Information:
Number of CPUs in the system = 2
CPU Map
cpu -----------------------------------------
slot | 00 | 01 | 02 | 03 | 04 | 05 | 06 | 07 |
state|caM |ca | | | | | | |
-----------------------------------------
| 08 | 09 | 10 | 11 | 12 | 13 | 14 | 15 |
state| | | | | | | | |
-----------------------------------------
c - Configured (CPU powered on)
d - De-configured (CPU powered off)
a - Active (configured and processes running)
i - Inactive (configured and idle)
f - Inactive with fail (inactive because of a CPU failure)
M - Monarch CPU (always Active)
C - Marked for re-configuration (Configured after next boot)
D - Marked for de-configuration (De-configured after next boot)
Any help would be appreciated.
Thanks in advance.
Solved! Go to Solution.

Re: How to disable one Core of CPU
Usually you can disable a complete CPU, but not single cores.
For PA RISC:
Main Menu: Enter command or menu > co
---- Configuration Menu ------------------------------------------------------
Command Description
------- -----------
AUto [BOot|SEArch|STart] [ON|OFF] Display or set specified flag
BootID [
BootINfo Display boot-related information
BootTimer [0 - 200] Seconds allowed for boot attempt
CPUconfig [
DEfault Set the system to predefined values
FastBoot [ON|OFF] Display or set boot tests execution
PAth [PRI|ALT] [
SEArch [DIsplay|IPL] [
TIme [c:y:m:d:h:m:[s]] Read or set the real time clock in GMT
BOot [PRI|ALT|
DIsplay Redisplay the current menu
HElp [
RESET Restart the system
MAin Return to Main Menu
----
Configuration Menu: Enter command >
Hope this helps!
Regards
Torsten.

Re: How to disable one Core of CPU
Use command 'model'
The CPU type installed?
How this is determined depends on the OS:
- 11.11/.23 - SAM -> Performance Monitors -> System Properties.
- 11.31 - use command 'machinfo'
As stated cores cannot be deconfigured, only CPU modules. However, with the above info we may be able to assist you further!

SolutionIn order to have your system register as a 1 way server, you need to have your model string adjusted to read 'rp3440-1' (or similar). This is possible, but requires an HP engineer onsite to do this. Another option is the use of the "downgrade" command from the BCH Service Menu. However this typically only works if your system was once upgraded.

Re: How to disable one Core of CPU
Unfortunately it doesn't seem to support rp3440.
What HP-UX version are you using?
