Processor addition/speed

gkornacki — Sat, 02 Dec 2006 14:49:27 GMT

I replaced 6 360mhz processors with 460's and HPUX is still reporting the speed as 360. Did I miss something? Am I supposed to change something to tell the OS about the higher speed?

I'm running 11.00. Is this a bug? What gives?

What type of machine? Some machines have dip switches on the mother board that tell the system what speed the processors are.

One is an l1000 and the other is a l2000

Thank for such a fast repsonse.

Of course they aren't 460's. 440's.

If you are referring to PA-8500 CPUs at 440MHz (NOT 460MHz), then yes they are supported. Make sure the CPUs and their support modules are installed in the proper order/sequence.

~hope it helps

Can you offer more info?

Proper order? Sequence? I took out the slower processors and put the faster in. I can't see how to to it any other way.

I do have both control units. The machines are performing great and sar -Mu is seeing all four. I went from two to four on the 2000 and upgraded the 1000.

Another question.

The 2000 and 1000 look the same internally. Both have room for 4 proc and plenty of mem slots and controllers, yet the 1000 won't take 4 processors and the mother board has room for them. What the?

The L1000 is firmware limited to 2 processors and 4GB RAM. There is also a limit on the PCI slots that are available for use.

The L2000 can use all 4 processor slots and have 8GB of RAM.

the l1000/l2000 have (or had) switches to tell the board how fast the processors were. NOTE: correct switch settings varied w/ rev level of the board involved.

Yes. It was DIP switches. Thanks
