Question about UNIX ioscan command

UNIX HP-UX
1

Hello there.

I have a question regarding the ioscan commnad.

When you execute the line ioscan -fnC processor it outputs a list of all processors in the machine.

Does this list displays only physical CPUs or does it displays each core?

For example, if i have a server with 1 Dual Core CPU, will the output be 1 processor or 2?

Thanks for the help.

Hmmm - dunno.
I'm off work tomorrow, but will check Thursday.

How do I detect multicore processors?

Thank you prowla! Looking forward to it.

Perderabo, thanks for the link. I'll take a look at it.
The problem is that i need to know the result of that particular line in a multi core server.

On Itanium, there's the "machinfo" command.

I would agree with machinfo command.

Very useful info there

otherwise
# cstm
# map
# select device (no for cpu)
# info
# infolog

But do remember - I am also a newbie....

Here's the output of the machinfo:

So, this machine has 4 cores, right?

Yes - 4 cores (I assume two dual-core CPUs).
How does it compare to the ioscan output?

If you do "Model", it'll show the model of the machine (rx3600, at a guess).

I would also recommend the cfg2html tool (freeware), which will produce a comprehensive report of the system's configuration in html format.

It reflects the ioscan result:

The server model is RX2660. 2x Dual core indeed.

Case closed, i guess. Four cores total.

Thanks for the help!!

So, turning the original question around, I can't see how to find out how many physical chips there are...

Thanks prowla.

What's your system config?

2x Dual Core as well?
