Physical Memory

Scott McDade — Wed, 16 Jul 2003 11:52:35 GMT

I have a C3750 running 11i and I would like to find out how much physical memory I have in the machine. Can someone tell me a way to view this?

Scott,

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

echo "phys_mem_pages/D" | adb /stand/vmunix /dev/kmem | grep phys | tail -1 | awk '{printf "%.0f MB\n",$2/256}'

It works.

even less typing :

dmesg | grep Physical

works only if the system error message buffer did not overflow, else go for:
grep Physical /var/adm/syslog/syslog.log

regards,
Thierry.

Hi Scott:

Another way:

# echo "selclass qualifier memory;info;wait;infolog" | cstm > /tmp/meminfo

You can see physical memory DIMMS and size and arrangement with this.

Regards!

Hi!

Try one of the following:

#echo phys_mem_pages/D | adb64 /stand/vmunix /dev/mem

or

SAM--->performance monitor--->system properties

or

cat /var/adm/syslog/syslog.log|grep Physical

or

dmesg

Regards,

Dario

The result of adb command shown above is in 4KB memory pages, so multiply it by 4096 to get the memory size in bytes.

Take a look at the kmeminfo command - it's the easiest way to get memory information. It also gives you many useful information...

If you have Support Tools Manager (STM) you can run cstm from the command line and select memory from the list of system resources. Depending on the system you have, memory may show up more than once. Add it all together. You can see some great info here including the actual memory banks and how much expandability your system has. You can also see memory parity errors. Good Tool!

Use command
# grep physical /var/adm/syslog/syslog.log
