Hi,
if you have access to perl:
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";'

Hi,

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

and you get it in bytes

Hi,

You can also try this

echo "selclass qualifier memory;info;wait;infolog" | /usr/sbin/cstm

Thanks gurus for all ur prompt reply...My machine has a 1GB RAM(1024MB)...But the perl command returned it as 1022MB(close call)...Also was curious to know whether it will (perl) with all HP-UX machines since it might be not be sometimes supported in some m/cs..or is it a in-built package of UX...

But the cmd

echo "selclass qualifier memory;info;wait;infolog" | /usr/sbin/cstm

worked like a charm

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)
--------- ---------
0A 256
0B 256
1A 256
1B 256
--------- ---------
System Total (MB): 1024

...This is de part of o/p I have got but my problem is whether I have to take the one in
Basic memory description or the System total in Memory Board Inventory...Was jus inquistive to know whether they might differ or not..Please suggest..

Hi Muthu,

Perl has been available in HP-UX for many years but (unsupported) versions of HP-UX may have the old Perl 4 version, or have both Perl 5 and 4 loaded at the same time. For HP-UX version 11-anything, Perl 5 is stadard.

cstm is part of the online diagnostics and normally installed by HP on every machine. However, some sysadmins either remove the diagnostics or reinstall HP-UX without them (neither is a good idea) which makes the cstm less portable. However, I would see the lack of cstm as a red flag and get it remedied. You can see an amazing amount of information through cstm:

CPU boards:
echo "selclass qualifier cpu;info;wait;infolog" | /usr/sbin/cstm

LAN cards:
echo "selclass qualifier lan;info;wait;infolog" | /usr/sbin/cstm

Memory:
echo "selclass qualifier memory;info;wait;infolog" | /usr/sbin/cstm

DIsks:
echo "selclass qualifier disk;info;wait;infolog" | /usr/sbin/cstm

[muthukumaran13]

So does that mean I can use that perl command without any further ado...or no harm in using
echo "selclass qualifier memory;info;wait;infolog" | /usr/sbin/cstm too...

[muthukumaran13]

Also while using the cstm command which one give you the RAM Size ..Basic memory description or the System total in Memory Board Inventory...Also plz let me know whether they might differ or not..

Thanks for all ur help so far :)
