physmem : symbol not found.

[Bill McNAMARA_1]

Hi,
one of my scripts is coming up with this:

echo physmem/D | adb64 -k /stand/vmunix /dev/mem | tail -1 | awk '{print $2/256 " Mbytes"}'
0 Mbytes

!

echo physmem/D | adb64 -k /stand/vmunix /dev/mem
symbol not found


echo phys_mem_pages/D | adb64 -k /stand/vmunix /dev/mem | tail -1 | awk '{print $2/256 " Mbytes"}'
1024 Mbytes

Also,
/usr/sam/lbin/getmem
48

48 whats??

So, who can tell me how much RAM, I have in this box.

Thanks,

Bill,

It is weird but /usr/sam/lbin/getmem should return your RAM (in MB). That number is too low on your system.

This is "what" outputs on getmem on my system, HP-UX 11.0, 9000/800.

# what /usr/sam/lbin/getmem
/usr/sam/lbin/getmem:

Bill,

Here's what I use:

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 '{print $2*4/1024}')
echo $MYMEM

What's your OS version?

Pete

[Pete Randall]

Sorry, I can't read. Your OS version is 11.0 so you need to use phys_mem_pages rather than physmem.

Bill,

Do you have glance on your box? If so, you can try:

# /opt/perf/bin/glance -m

and look for "Phys Mem:" at the end of the line next to the last. To quit glance, type "q".

Hai

[Bill McNAMARA_1]

I don't have glance installed, but if I did am nearly positive that it will give me yet another value...

Is there not an easy way? or at least one that works?!

Later,
Bill

[Pete Randall]

Bill,

I really can't read, I guess. You did try phys_mem_pages. I tried both my method and yours on my 11.0 N-class and came up with 8192 Mbytes. /usr/sam/lbin/getmem, however, came up with 192.
So, I'm with you - 192 what?

What does dmesg say about memory?

Pete

[Hai Nguyen_1]

Bill,

How about this?

# dmesg | grep "Physical:"

The first value is your RAM in KB.

Hai

[Bill McNAMARA_1]

echo phys_mem_pages/D | adb64 -k /stand/vmunix /dev/mem
result is 1024.

Glance is installed:

Total VM : 161.1mb Sys Mem : 70.8mb User Mem: 311.4mb Phys Mem: 1024mb
Active VM: 113.2mb Buf Cache: 512.0mb Free Mem: 129.8mb


But I don't believe it...
I think I've got more like 256 MB RAM installed?
Unless someone added some?

Bill

[Tom Geudens]

Hi,
This might do the trick :
#echo "selclass qualifier memory;info;wait;infolog" | cstm | grep "Total Conf"

Regards,
Tom

[Sajid_1]

Bill,

I think the system came up with less RAM first when it installed and you 've added some more memory in that. In this case the 'getmem' utility will give you wrong answers. If you invoke sam, performance monitors, system properties, you will get the correct value.

[Pete Randall]

Bill,

And what about Ignite's print_manifest |grep Main?

Main Memory: 8192 MB

Pete

[Bill McNAMARA_1]

From syslog.log (dmesg full of other garbage)

Jul 30 09:59:45 pereal vmunix: Memory Information:
Jul 30 09:59:45 pereal vmunix: physical page size = 4096 bytes, logical page size = 4096 bytes
Jul 30 09:59:45 pereal vmunix: Physical: 1048576 Kbytes, lockable: 325372 Kbytes, available: 385300 Kbytes

Bill,

It's really beginning to look like you've got 1GB. Must be the memory fairy paid you a visit.

Pete

[Bill McNAMARA_1]

STM:



Basic Memory Description

Module Type: MEMORY
Total Configured Memory : 1024 MB
Page Size: 4096 Bytes

Memory interleaving is supported on this machine and is ON.

Memory Board Inventory

DIMM Slot Size (MB)
--------- ---------
01 512
02 512
--------- ---------
System Total (MB): 1024

I guess we do have 1G..
I'm kinda wondering where it came from!

Great!

so swapinfo output then, how can I interpret that?

Later,
Bill

[Hai Nguyen_1]

Bill,

At least now dmesg in syslog.log and glance agreed on the amount of RAM you got on the box.

I'm looking for some other way to cross-check.

Hai

[Sajid_1]

From TKB document - A5564404 - "At version 11.0 of HP-UX, the physmem parameter has
been replaced by the phys_mem_pages.

You should therefore rework your command syntax as
follows:

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

Other options are:
# stm
# sam
# reboot and interrupt it, then go to information menu.
