diff CPU speed in BL870 blade

Hi,
We have installed 2 additional CPUs to the existing BL870 blade. At the boot screen, it complained CPU speed being diff. What will be the effect to this? There are 4 dual-core CPUs
in this box. Will the all 4 CPUs go with the slow speed like the disks do?

Thanks in advance.

Hi Lucy,

Please share the exact message that you are getting.

Also do you have icod or icap enabled in your system?

Re: diff CPU speed in BL870 blade

To find out processor speed,run :
# echo itick_per_usec/D | adb -k /stand/vmunix /dev/mem

This will be the speed in MHz.

# icod_stat

Re: diff CPU speed in BL870 blade

At the boot screen:
This boot experienced the following problems:
Warning[42]: CPU's with different core freqs installed.
Address the warning issues as soon as poosible.
Redisplay list with 'info warning' at EFI shell.
Press [Space] to continue...

I hit the space and the system came up smoothly.
Here are the CPU speed:
cpu1: Dual-core Intel Itanium 2, 1600 MHz
cpu2: Dual-core Intel Itanium 2, 1600 MHz
cpu3: Dual-core Intel Itanium 2, 1666 MHz
cpu4: Dual-core Intel Itanuim 2, 1666 MHz

cpu1 & cpu2 are the original BL870 CPUs.
cpu3 & cpu4 are the new ones added in.

SHELL> info all

Look for cpu speeds and cache sizes under:

PROCESSOR MODULE INFORMATION

Re: diff CPU speed in BL870 blade

Maybe you have different types, please post

Shell> info all

and/or

Shell> info cpu

like this:

Shell> info cpu

PROCESSOR MODULE INFORMATION

# of L3 L4 Family/
CPU Logical Cache Cache Model Processor
Module CPUs Speed Size Size (hex.) Rev State
------ ------- -------- ------ ------ ------- --- ------------
0 4 1.6 GHz 9 MB None 20/00 C2 Active
1 4 1.6 GHz 9 MB None 20/00 C2 Active



Run the command from EFI shell!

Hope this helps!
Regards
Torsten.

Re: diff CPU speed in BL870 blade

is the issue the same if you swap them around into each others slots , may be a stepping glitch..

see if there is an update from intel for that cpu

Re: diff CPU speed in BL870 blade

in bios can we see cpu frequencies multiplier or clock freq may be wrong.

Re: diff CPU speed in BL870 blade

Hi,
The machine is up and running. I can not take it down now. The CPU speed command returns error on this HPUX 11.31. Any idea?

/stand/vmunix /dev/mem

adb: info: Option -k is deprecated.
