OS is not detected CPU and memory
Hi,

Server AIBVRFCC failed POST while booting on 06/28/2009. Server is up, but OS cannot see two CPUs (CPU 0 and CPU 2) and half of the installed system memory (8 GB is physically installed but only 4 GB is seen by OS now).

Code:
bld00016:root psrinfo
1 on-line since 06/28/09 05:51:36
3 on-line since 06/28/09 05:51:14

Code:
bld00016:root prtconf | grep Mem
Memory size: 4096 Megabytes

POST error messages on console:

Code:

Reseat the boards and powerup the server again. It might not be seated correctly in the slots(maybe). Unlikely that it should fail
