dl145 second cpu not recognized

Hi,

I checked this forum but didn't see any entries concerning this basic task.

I recently installed a DL145 G2 processor upgrade kit as per instructions and now have 2x opteron 252s on my board.

The BIOS doesn't seem to have an entry to list CPUs and the OS (RHEL4-U3) doesn't see the 2nd cpu.

The motherboard has a printed label for jumper-settings (J1/J2) corresponding to one/two cpus. These jumpers are not present on my board (empty solder-holes), near the reset jumper (J5) which is also empty.

Can anyone advise ..? I hope there is a simple BIOS or OS tweak as I don't want to add jumpers.

Thanks ...

Phil.

Re: dl145 second cpu not recognized

Do you have a seconf processor power module? And are the CPUs the same stepping?

Re: dl145 second cpu not recognized

Hey Phil,

Before installing 2nd cpu make sure bios firmware is latest part no for both procs are the same it means both are same stepping and it could be new proc is a bad try 1 proc at a time in proc slot 1.

Cheer :)

The server markings:
PID: 360519-B21
HP ProLiant DL145

BIOS upgraded to the latest I could find:
http://h18023.www1.hp.com/support/files/server/us/download/23325.html

The problem:
When both H0 and H1 cpu sockets are populated, the 2 PPM
sockets populated as well, with 2x512MB CL2.5 ECC REG in
H0_DIMM0/1 and same make and model another 2x512MB CL2.5
ECC REG in H1_DIMM0/1 BIOS incorrectly shows "CPU Count: 1".
The 2 LEDs H0_PRESENT and H1_PRESENT are both correctly lit
green. Linux incorrectly finds 1 CPU, although the same
bootable CD finds 2 on my Athlon X2 desktop machine(to
confirm the kernel is dual cpu capable).

Both sets of CPU/PPM/memory tested in single CPU mode (H0
cpu socket populated, PPM0 populated, H0_DIMM0/1 populated)
BIOS correctly shows "CPU Count: 1". The H0_PRESENT LED is
lit green, H1_PRESENT LED is correctly off. Linux correctly
finds 1 CPU.

I cant find a reason why the BIOS wouldnt accept and use the
second CPU. Any help will be greatly appreciated !
