How many cpu´s ?
2007-12-25 11:44:00
Almost people suggests using these commands:
/usr/platform/`uname -m`/sbin/prtdiag
mpstat
psrinfo -v
But, I solved my problem change to 0 this eeprom setting:
.upa-noprobe-mask
and I could disable/enable a CPU back by psradm command.

My original question:
Hi Admins
I want to know how many cpu´s exists in my system, without turn off this
system.
I tried to use ´dmesg?but the result is confused for me:
dmesg | grep -i ultra
cpu0: SUNW,UltraSPARC-II (upaid 0 impl 0x11 ver 0x20 clock 296 MHz)
root nexus = Sun (TM) Enterprise 250 (2 X UltraSPARC-II 296MHz)
prtdiag shows:
========================= CPUs =========================
Run Ecache CPU CPU
Brd CPU Module MHz MB Impl. Mask
--- --- ------- ----- ------ ------ ----
SYS 0 0 296 2.0 US-II 2.0
I don´t know if I have just one CPU or if there are two and the second is
disable or is not working
fine.
Any help will be very appreciated.
Thanks in advance
Gabi
