How much RAM (real memory) does my machine have? From: Michael Abel/resnova



As root: bootinfo -r
As any user: lsattr -E -l sys0 -a realmem

lsdev -C -c memory

shows all memory adapters. On MCA systems one may add up the values
displayed for each memory card in order to sum up to the amount of
total memory. On PCI systems only one item (mem0) is
displayed. Additional information may be displayed with

lsattr -E -lmem0

These commands were tested on various IBM systems running AIX relases
3.2.5 and 4.1.4
