C'mon, you know the routine: IOS-level? Underlying hardware? Do you use a HMC? What does the profile say? And what else might be interesting to know about the system?

In one word: information! Please!

And, btw., have you considered this article?

thanks Bakunin

but there is no profile for the whole VIOS machine, Virtual I/O Server
although it is very similar to HMC

Please see the screen shot below

This is why i asked you if you use a HMC - you don't, but use IVM instead.

The IVM screen says the total system memory is 16GB. Do you have all 32GB activated? IBM usually delivers its machines configured for CuOD (customer upgrade on demand) and you can use only a part of what is physically installed until you buy a license for the rest.

Did you check the error log? Maybe some memory/memory controller is broken and was deactivated by the system. Have you checked the ASMI?

I hope this helps.

Checked CoD, through IBM Capacity on Demand: Activation code
It is not Configured for COD

Checking error report doesn't show any red flags

Now remaining is ASMI
i wish there was a way to enter ASMI from the IVM itself, but someone has to be at the machine connect it to the port or put it on the lan.

I will check ASMI and update.

THanks

I didn't mean errpt. In the IVM menu you find a point reading "Serviceable Events" or similar - look there. This is the "errpt of the hardware".

I hope this helps.

[solved]

Went through ASMI in standby mode

1) clear all the logs
2) Configured the deconfigured memory modules

Power off the machine completely

Power on the machine.
