Try any of these:

# dmesg (look for physical memory area in bottom)

# sam -> performance monitors -> system properties

# stm -> and check for RAM info

Also, check fromm the boot console menu

Nag,

I use this little script:

HPUX=/stand/vmunix
MAJORREV=$(uname -r | cut -f2 -d .)
if [ $MAJORREV -ge "11.0" ]
then
MYSYMBOL="phys_mem_pages"
else
MYSYMBOL="physmem"
fi

MYMEM=$(echo "${MYSYMBOL}/D" \
| adb $HPUX /dev/kmem \
| grep "${MYSYMBOL}: *." \
| awk '{printf "%.0f MB\n",$2/256}')
echo $MYMEM

Hi Nag,

How much memory do I have
a5:/ 112 # echo "selclass qualifier memory;info;wait;infolog" | cstm | grep 'Total Configured'
Total Configured Memory : 2048 MB
a5:/ 113 # echo 'memory_installed_in_machine/D' | adb -k /stand/vmunix /dev/mem | perl -nle'/(\d+)/&&print$1*4,"k"'
2097152k
a5:/ 114 # grep Physical /var/adm/syslog/syslog.log
Aug 25 08:01:07 a5 vmunix: Physical: 2097152 Kbytes, lockable: 1562360 Kbytes, available: 1801856 Kbytes
a5:/ 115 #

Hi,

There are couple of ways

grep -i "physical" /var/adm/syslog/syslog.log. You should see Physical: xxxxx Kbytes. You will get it only if you don't recycle syslog periodically.

If you have online diagnostics

echo "map;selclass type memory;info;wait;infolog;dong;ok;q" |cstm

Full proof method:

echo "phys_mem_pages/D" |adb -k /stand/vmunix /dev/kmem

Multiply the value you get in the above with 4 to get the memory in KB.
