How do I disable a core(or more) while boot up in Solaris 10?
Hi,
I have 4 cores in my PC. I know how to disable a core using psradm -f command after boot up. But I want to disable while boot up (permanently).
1) I want only 1 core. How to disable all other cores while boot up?
2) I need to disable 2 cores. How to disable all other cores while boot up?
I need the best way.
Thank you.
