Vpar Memory missing in Superdome 2

[vpar]

Hi,

11.31 & SD2

Memory sizing is difference between npar and vpar. I know some missing memory size use for formware and vpmon but superdome 2 do not use vpmon. Alos "vparstatus -m" command have no in Sperdome 2 vpar.

Like below, vpar memory is 1G in size missed or 2G missed.

What happened in my system?

I post parstatus output.
Before vpar, npar shows 2 G missed.
In here, Total memory size is 96G but ILM (10G) plus SLM(84G) show 94G. Why?

It's hard to read the output above, better attach it.


The system will reserve a certain amount of memory, e.g. for I/O, so you cannot use 100% of it.

Hi

parstatus of SD2 report defferently with old machine like(rx series,etc).

On SD2, Total good memory 90G, ILM is 10 and
SLM is 84G. I can't see 2G.

On other machine, Total good memory is same with ILM+CLM.

I think it is npartition issue before OS memory(vpar issue)

[Torsten.]

As said before, the system will reserve memory space for certain I/O cards in the lower memory segments for up to 16 possible vPars on this platform.
