Re: rp8400 and missing processors
when the npar is booting - go into vfp and monitor the cells when they're booting; search for "E" on the left of the cell. additionally - you can check logs in MP (sl -> show logs) and seek for hw problems.
further - when you run ioscan: how many cpus do you see? and what if you run parstatus? what in stm? what in glance / top? what in syslog.log when system started? does all these sources show the same number of cpus?

Re: rp8400 and missing processors
The best way is to use utilities like Partition Manager in SAM and stm from command line. You can alanyze the partition configurations. Sometimes the server disables the processors after the reconfigurations. You should be able to see those "disabled" processors using those tools. In order to understand the reason enter the MP and view the MP logs that correstpond to the processor tests/activation.
Regards,

Re: rp8400 and missing processors
They could be Icod CPUs, however if I run icod_stat, I cannot see them.
Some cut and paste:

Re: rp8400 and missing processors
You have all the CPUs on the box but while creating the partition you have not added the cell board 1 that is the reason you are not able to see those 2 CPUs.
ypu have to execute parmodify command and then add the cell board 1 as well in the current partition and then reboot the server.
I hope this will resolve the issue.

Re: rp8400 and missing processors
there are only 6 CPUs installed on your ssytem..
Parstatus output shows that cell board 1 has only 2 CPUs, however it is capable of 4 CPUs.
So physically only 6 CPUs are present...

Re: rp8400 and missing processors
I'll need to consult the previous owner.
Anyway, thanks for all the responses.
