Get installed memory-size from HP-UX

[Maximilian Voss]

Hi guys,

I'm new to HP-UX and I'd like to know how may I retrieve the actual memory-size from HP-UX.
About 4 weeks ago, somebody told me to use /usr/sam/lbin/getmem, but when I've got a machine with more than 1 GB RAM, I get the value 72MB which is for sure wrong.
I talked to some guys and they told me to ask the kernel directly, but I have no idea how.
I have HP-UX V11.xx systems.
swapinfo shows me available memory, but not how many is installed.
Is there somebody who can help me?

Best Regards

Max

Hi Max:

This will show you the physical memory installed and the layout of the same:

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

You can either gather it from the kernel message buffer:

enter dmesg and look/grep for Physical memory

or, if You have the Support Tools installed using:

echo "selclass qualifier memory;info;wait;infolog"|cstm | grep "Total Configured Memory"


The second one works better in my opinion.

Hi Max;
cat /var/adm/syslog/syslog.log|grep Physical


Good luck

Actually swapinfo does NOT show you installed memory. It shows you the amount calculated for use as 'pseudo-swap' space. Have a look at the swapinfo man page for more info.

To see the number of DIMMs installed (this assumes you have diagnostics installed):

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

If you want to see total physical memory:

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

[Patrick Wallek]

My last command should be:

# grep -i physical /var/adm/syslog/syslog.log

[Andrew Belville]

dmesg will give it to you (if you still have the boot process in the buffer)

Glance will show you (press 'm' for memory information).

and this c code will tell you (original author not known):

#define _PSTAT64
#include
#include
#include

int main(int argc, char *argv[])
{
struct pst_static pst;

if (pstat_getstatic(&pst, sizeof(pst), (size_t)1, 0) == -1) {
perror("pstat_getstatic");
return 1;
}

printf("physical memory size %llu bytes\n",
(unsigned long long) pst.physical_memory * pst.page_size);

return 0;
}

Hi,

for 11.11 and 11.0 it's:
echo "phys_mem_pages/D" | adb /stand/vmunix /dev/kmem|grep phys|tail -1|awk '{printf "%.0f Mb\n",$2/256}'

You can also see it when the machine boots up - it's displayed during the boot process.
Also you can see the single RAM DIMM's when you interrupt boot process and let display the memory.

Hi guys,

thanks for your high-speed posting.
All the stuff you've posted doesn't work ;(
I don't get any result. Asking dmesg or syslog doesn't work, because they're flooded with errors of some software and the machine had it's last reboot some month ago ;(
I asked someone from openview and he told me, that it's possible to ask the kernel itsself, and he told me how, but I can't remember. And he's currently on vacation.

Bye

Max

#!/bin/ksh

GetKernelSymbol()

echo "$1/D" | \
adb -k $hpux /dev/kmem | \
tr "\012" " " | \
read junk junk2 kval
}

hpux=/hp-ux
rev=$(uname -r | cut -d. -f2)
if ((rev > 9)); then hpux=/stand/vmunix ;fi
/bin/uname -a
GetKernelSymbol "processor_count"
print CPU Count: $kval

let speed=kval/10000
print CPU Speed: $speed MHz

if ((rev > 10)); then

else

let mb=kval*4/1024 # convert pages to MB
print RAM Size: $mb MB

Thanks Volkmar!
It works, and that was exactly the command he gave to me.
Lots of thanks guys for your help.

And you can also compile this c program called memdetail...

Output like:

# memdetail
Memory Stat total used avail %used
physical 4088.0 2468.4 1619.6 60%
active virtual 5475.0 724.3 4750.7 13%
active real 1450.5 280.2 1170.3 19%
device swap 20480.0 5230.0 15250.0 26%

You should definitely install the Support Tools, without it You don't have hardware monitoring and problems might go unnoticed.

hi,

use

dmseg | grep memory

Try this:

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

[Hoang Chi Cong_1]

If you have installed the Support Tool Manager, you can use this command:
echo "sc qualifier memory;info;wait;infolog" | cstm

Hi Max

Use following command to get physical memory available in hp-ux server:

#dmesg |grep "Physical"

Mahesh

[V. Nyga]

Comon boys - can' you read:
dmesg or syslog doesn't work for Max!

@Max - maybe you should close the thread now ...

The simplest method is sam. Just start sam and select:

Performance Monitors -> System Properties

[John M. Jones, III]

Simplify all your request in the forum Max.I like "Bill" advise.All have missed the first initial point.. You are new to it HP-UX. Great O/S btw..Here an easy way to get all information regarding all resources attached, configured or assigned. SAM will become your best bet in any and all operation as well. SAM is forgiving..I hesitate to say this and will tell you if you are about to step on it and does alot under the covers for you. IF by change you are fimiluar with print_manifest it too is very informative cd /opt/ignite/bin
run ./print_manifest Get Admin Book and a test server and have at it...
