Question about UNIX ioscan command
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.

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....
