Summary: How many cpu´s ?

Date: Mon Nov 20 2000 - 10:41:13 CST


Almost people suggests using these commands:

/usr/platform/`uname -m`/sbin/prtdiag
psrinfo -v

But, I solved my problem change to 0 this eeprom setting:


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

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

Any help will be very appreciated.

Thanks in advance
