Processors on rp4440-8, and HP-UX
We have an rp4440-8 with HP-UX. All the HP bill of materials, and licensing refers to our configuration as a 4 processor system. It has 2 system boards with dual core processor.
ioscan and top only see 2 processors. Is this correct ? Can I not see all 4 processors from the operating system ?

Re: Processors on rp4440-8, and HP-UX
I didn't think the rp4440's were cell based architecture. (But I could be wrong, we haven't purchased one yet.)
There should not be anything preventing you from seeing all 4 processors from an OS perspective. (Assuming they are all there and configured.)
Do you have online diagnostics? can you run cstm or xstm to look and see what they see?
Short of that, can you reboot the server, interrupt the boot process to the BCH, and see how many processors are there?

Re: Processors on rp4440-8, and HP-UX
You can use pstat_getdynamic call to find out the actual processors and active processors.
You can use psd_max_proc_cnt and psd_proc_cnt fields of pst_dynamic structure defined in /usr/include/sys/pstat/global_pstat_body.h

Re: Processors on rp4440-8, and HP-UX
Check the system with glance. It should give you more details. If you don't have glance you can download an eval version.
Otherwise the command dmesg might show you the bootup messages...also in /var/adm/messages...

Bob

If that doesn't show 4 processors, then run sysinfo301 - attached like so:
/usr/local/sysinfo/sysinfo -a -b -o /usr/tmp/`hostname`.sysinfo
The look view /usr/tmp/`hostname`.sysinfo

Re: Processors on rp4440-8, and HP-UX
You have 4 physical cpu's. That is 100% right. They have two CPU cores on each so on the system you will have 8 CPU's when you look at it from the OS level.

Re: Processors on rp4440-8, and HP-UX
And software licenses are on cpu level.
Not yet taking in account the same confusion we have now with the double core CPU's.
How do we count them? The hardware view or the software view... ;-)

Re: Processors on rp4440-8, and HP-UX
Well the licensing will depend on the app and the app rules.
The app would see 8 CPU's so it will be 8. Some apps allow you tobuyer smaller blocks etc.

Re: Processors on rp4440-8, and HP-UX
if you ordered an rp4440-8 then you should see 8 processors not 4 or 2
this would be made up from 4x dual core cpu's installed on the baseboard. 2 on the top and 2 underneath.
I would check first at pdc level on bootup to see if all 8 proc are seen. If not detected then they wont work in unix. You can also easily check the baseboard for installed cpu's
Your licences should also reflect 8 processors.
hpux and oracle and other apps price per cpu
1x dual core cpu = 2 lic required.
Sounds like you may have to call HP as they have misconfigured your server.
