RHEL not recognizing dual core CPU's
We have installed RHEL 5.2 on HP rx6600. cat /proc/cpuinfo command says that there are 4 processor. But these processor are dual cores. So totally there are 8 cores.
What command in Linux will tell us that the total number of cores in then system is 8?
Correct answer will be awarded full points.
Thanks,
Senthil.

Re: RHEL not recognizing dual core CPU's
uname -r
cat /proc/cmdline
Have you started with an SMP kernel enabled?

Unless you're running RHEL 5 Advanced Platform, the problem is the number of physical CPUs. To support more than 2 physical CPU sockets, Advanced Platform version is mandatory.
2 physical CPUs allowed x 2 cores each = 4 CPU cores total available to the OS and applications.
Check the system boot messages. If they scrolled by too fast, run "dmesg | less". You may find that the kernel is trying to tell you exactly what the problem is.
