I'm am new to AIX and for some reason the system will not see all the memory loaded on the box. Please note:

# bootinfo -r
2228224

# lscfg -vp

Looks like the lpar only has 2G, but as you don't know which 2G lscfg lists all the memory in the box. I've noticed the same with processors, an lpar may only have one of 16 processors but lscfg shows all 16.

Thanks DukeSSD I'll look into this further.

As all CCIN numbers are the same and you MUST have some non COD memory we can be sure none is COD / CUoD so I can only think it is an LPAR with 2GB assigned.

type lparstat -i as root and paste the output please

Does:

help?

I was told that in order to allocate the extra 8GB of memory to the LPAR that currently sees 8GB the HMC needs to be updated to the latest version. The current version I have is:

Version 4
Release: 3.1
HMC Build Level 20041115.1
MH00186: LIC Update Fix (11-19-2004)

Thanks,

Thanks for the link Ken.

 

[p5wizard]

Also compare the output of

lsattr -E -l sys0|grep mem

and your

bootinfo -r

output.

lparstat shows 8GB minus the LPAR/pHYP memory overhead, seems normal to me:

Online Memory : 7808 MB
Maximum Memory : 8192 MB
Minimum Memory : 128 MB

Note: topas will also indicate server or partition memory size: look for MEMORY section on the right hand side of the screen, halfway down.
