pset_info shows a processor in off-line status and psradm cannot start it

Hi,

Our client has 4 Alpha servers 1200, already upgraded to two CPUs.

I have tried the psrinfo command and it shows that CPU 1 is off-line. When I performed the following command psradm -a -v 1 it says that the CPU is already running.
psrinfo again shows that CPU is off-line.

pset_info is showing only one CPU (0) in set ID 0 and the second CPU is not displayed.

FOr info: the cpu_enabled variable is set to f, and sh cpu displays that both CPUs 00 and 01 are active.

Can anyone help me on this issue?

Thanks in advance

can you try
psradm -n cpu_number

Re: pset_info shows a processor in off-line status and psradm cannot start it

Thanks for replay

hereafter is the result of the command:

blds2>root> psradm -n -v 0
processor 0 already on-line.
blds2>root> psradm -n -v 1
processor 1 already on-line.

I read an explanation in one of the Solaris book, that the meaning of off-line means the CPU doesn't process kernel threads only, but other interruptions can still be run on off-line CPU. What do you think ? is that true for UNIX 4.0 e

Re: pset_info shows a processor in off-line status and psradm cannot start it

Hi,

you mentioned that the HW is "already upgraded to two CPUs".

I recall a issue where one added another CPU but forgot to enter
the additional OSF-BASE license to it.

Look here:
http://licensing.hp.com/swl/view.slm?page=alpha

So...on a system (AS1200) with a single CPU you'd see OSF-BASE = 25
but after you upgrade to 2 CPUs you d have to add 50 Units more to
get 75 OSF-BASE Units in summ.

The command to display how much units are installed is
# lmf list for osf-base
(could as well be that you see -unlimited- there, that would suit as well)

Its quickly checked, thats why I thought worth mentioning it.

Re: pset_info shows a processor in off-line status and psradm cannot start it

Hi,

First time when we have upgraded AS 1200 to 2 CPUs, we had licence issue. We were able to log only with root account, other accounts were disabled or not accessible. OSF-BASE database was updated with a new licence in order to support double CPUs.

I checked out the OSF-BASE, so the total number of users is unlimited.

Thanks in advance.

Re: pset_info shows a processor in off-line status and psradm cannot start it

Output of:
# lmf list full
would be helpfull.
Did you upgrade the firmware after the second CPU was installed?
Can you post output of:
>>> show config

Hi,

Please tell me how to get a text file from SRM console to the floppy, so I can show you the result of the commands as >>> sh config and >>> sh cpu. For the meantime hereafter a result of the lmf list command:

Re: pset_info shows a processor in off-line status and psradm cannot start it

When you shutdown a server you get ">>>" prompt. This is called SRM prompt or "console mode".
So, when you will be able to shutdown the system, do it and send output of requested commands.

Re: pset_info shows a processor in off-line status and psradm cannot start it

Hi,

I will clarify my question. When I am in console mode I am doing the following commands: sh config > config.txt
sh cpu > cpu_status.txt

I need to get these text files and post them for you, otherwise I have to write the result of sh config manually. Is there any way to get these file on the floppy?

No, you can not redirect to file.
Connect a terminal emulator to console and capture output.
And did you do firmware upgrade after installation of second procesor?

Hereafter the result of sh cpu:

No we did not upgrade the firmware after adding the second cpu.

Re: pset_info shows a processor in off-line status and psradm cannot start it

Looks like both CPUs are configured.
And also looks like you have enough licenses.
Not sure what can be the problem, but I would upgrade the firmware.
Upgrade the firmware and after that send output of:
>>> show config
# prsinfo -v

Re: pset_info shows a processor in off-line status and psradm cannot start it

we have exactly the same problem on AS1200 ruuning under 4.0e the firmware update was done after installing CPU
psrinfo and online -v reply to us the same as WW346672 question in november 2009

No solution for the moment

Re: pset_info shows a processor in off-line status and psradm cannot start it

Here is the solution for my problem

The problem is due to subsystem generic lockmode parameter wich is set to 1 in sysconfigtag
Commenting lockmode or setting to 0 and setting cpu-enable-mask to 3 solve the problem

--------------------------------------------The mode of the simple lock primitive package within the kernel. Four sets of locking primitives support various combinations of real-time (RT) kernel preemption, symmetric multiprocessing (SMP), and lock debugging with lock statistics.

When only RT is required (lockmode=1), the simple lock operations maintain a "preemption blocking" count.
