rx7640 showing only one CPU!

Hello,

 

I have two rx7640 running hp-ux.  Node 2 is showing only one CPU (two cores) in hp-ux (machinfo) while Node1 is showing TWO CPUs (four cores). 

 

When I checked in MP, I see only cell board #1 intalled and TWO cpus on them. Therefore I should get four CPUs in hp-ux as the other node. Is there any other place to check?  Please help...

Re: rx7640 showing only one CPU!

Hi ,

 

According to the DU output , We can see Both Node 1 and 2 has 2 Physical processors, But in Node 2 shows only one Physical processor in Machinfo.

 

Please paste info cpu output from EFI and see any CPU deconfigured messages in MP Logs(SEL and FPL)

 

Please update if the system faced any reboot or any hung issue in recent times?

 

HTH,

Surendar

Re: rx7640 showing only one CPU!

CPU could be disabled or just not visible for any reason.

 

Is it a vPar by chance?

 

# vparstatus

 

or even icap?

 

# icapstatus

 

# parstatus

 

Try to format the output or just attach.


Hope this helps!
Regards
Torsten.

Re: rx7640 showing only one CPU!

Thanks for your help..

Please find the attached output. There are two inactive cores on node2 . How can I get it working in hp-ux?

 

On both nodes;

#vparstatus
sh: vparstatus:  not found.

So we know 1 CPU (2 cores) are disabled.

 

Try to enable hem from EFI and see what happens.

 

 

From EFI do

 

Shell> cpuconfig

CPU threads are turned off.


Shell> help cpuconfig
Deconfigure or reconfigure cpus


Hope this helps!

Re: rx7640 showing only one CPU!

Hi,

The c

puconfig command displays the config/deconfig state of processors in the system and allows the user to configure or reconfigure processors.

 

Syntax
cpuconfig <cpu> <on|off>

 

Parameters
<cpu>: specifies a processor
<on|off>: state to set the processor

 

 

To enable or disable Hyper-Threading, use the EFI cpuconfig threads on or cpuconfig threads off command. For more information, enter help cpuconfig at the EFI Shell prompt or see the appropriate hardware documentation.

 

HTH,

Surendar
