additional CPU

[jarcar]

RS6000, 7025, 6F1 AIX 4.3.3

I have just replaced 1CPU with 2CPU's.

(RS64 III, 1W, 450 MHZ, 2MB L2
with
RS64 IV,2-WAY SMP,8MB L2 CACHE)

Are there some system settings that i should change, tune etc. ?

Check of bos.mp is installed (lslpp -l)
diag -a
lsdev -Ccprocessor or bindprocessor -q

This should be enough.

regards,
Geert

I'd be surprised if the MP fileset wasn't already installed seeing as
the mp fileset is installed if the system is MP capable even if only one
CPU is actually present.

You might want to install bos.mp and then relink /unix to
/usr/lib/boot/unix_mp and reboot to use the 2nd processor. If you've
got any licensed software, you might need to update the licenses.

Thanks all for sugestions

I have one more question about vmstat and CPU.

I have replaced 1 CPU with 2 CPU's.
I have checked for all things you have mentioned (everythig is ok).

I use vmstat to monitor performance.

everyday at 6 am i start this : vmstat 1800 32


After CPU replacement I've noticed that "r" column is allways "1" .

Is it normall behavior with 2 CPU's ? Why ?
