prtdiag and memory banks

hi,

we have an e6900 and my sys admin says that the number of processors and memory were reduced to 4 and 8GB. However, a prtdiag |grep Memory returns 16GB of memory. So what is my system's memory? psrinfo returns 4 online and 4 offline CPUs.

Thanks.
Kumar

If memory serves correctly . . .

If I'm not mistaken, the RAM associated with any specific processor will be mapped out of memory. . . so both answers are right. Under this theory, there may be 16GB of RAM physically installed in the system, but if half the CPUs were offlined, the corresponding RAM will be mapped out as well.

I will do some research and report back if I can find substantiating documentation or links.
