Hi,
Please see:
http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=439070

To see the physical memory lay out:
STM. (Support tool manager)

echo "selclass qualifier memory;info;wait;infolog" | cstm

For memory size:
perl -e 'local($PSTAT,$PSTAT_STATIC,$mem_info,$PSTAT_STRUCT)=(239,2,"\0"x120,"LI4L");
syscall($PSTAT,$PSTAT_STATIC,$mem_info,length($mem_info),1,0);
print "RAM=".int((unpack($PSTAT_STRUCT,$mem_info))[4]*((unpack($PSTAT_STRUCT,$mem_info))[5])/(1024*1024))."\n";'
or use SAM

For number of slots/occupied slots, use STM.

echo "selclass qualifier memory;info;wait;infolog"|cstm

For monitoring memory usage, you can use glance/vmstat/pv etc.

glance -m
vmstat 1 3
