What is the command to find out total physical memory installed in an hp-ux machine?

Dmesg|grep physical & wc -c /dev/mem are does not seem to be working.

Thanks!

hi
there is a typo that you are making in the dmesg

do like this

run this as the root user.

#dmesg| grep -i physical

if errors are found please post the errors.

What does the #swapinfo -tam and #top show

also you can see running
#print_manifest
#cstm also can be helpful.

Regards
Sujit

There are many ways to do this - here are a couple:

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

Support Tools Manager (STM) RAM info:

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

Hi Pradeesh,

Use these commands.

# echo "selclass qualifier memory;info;wait;infolog" | /usr/sbin/cstm | grep 'Total Configured'
# echo "selclass qualifier memory;info;wait;infolog" | /usr/sbin/cstm | awk '/Total Configured/{print $5}'|head -1

You can also use SAM to find the physical memory.

Hi,
# To get RAM size in KB
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";'

HTH,
Art

Hi Pradeesh ,

You can use "machinfo" also

#machinfo|grep Memory
