CPU Speed Conflict?

[Steven Chen_1]

Hi,

We have K260 with 2 CPUs. According to some posting in this forum, the CPU speed should be 180mhz. But I observe that speed happens to be 120mhz on rebooting screen.

Would someone verify that? The importance of it is if the CPU is not the proper one, we may have problem installing hpux11 (32bit or 64bit).

Thanks a lot,

Steven

Hi Steven,


First of all to determine the processor speed, you could use

echo itick_per_usec/D | adb -k /stand/vmunix /dev/kmem

This would return your processor speed in MHz.

Now looking at the HP site, The processor speed for a K260 is 180MHz, the speed for a K220 is 120MHz. A nice comparision can be found at http://www.hp.com/products1/unixservers/midrange/kclass/infolibrary/index.html

Ramesh,

Thank you for the help. I have not used adb before and would like to know if it is safe to use it while many db applications are running.

Hi Steven,

The K260 is indeed a PA8000 at 180MHz.

I think you may be confusing Processor Speed (180Mhz) with Central Bus Speed (120 MHz).

To verify, interrupt the boot process and enter the firmware monitor.

INformation->PRocessor.

This should display both the processor speed and the central bus speed.

If you had CPU's in your box with different speeds your box would not boot and you would have a series of FLT codes cycling endlessly in the lower left corner of your screen.

Hi Steven,

adb can be run while other applications are running.

Here is a link for a tutorial on adb (somewhat old )
http://docs.hp.com/hpux/onlinedocs/92432-90006/92432-90006.html

This link tells you about the feature of adb on 11i

This discussion in the forums on adb gives us some useful information (especially the response by Eran Maor)

This should get you started on adb
