Adding RAM to L1000

I intend to add RAM to an L1000 running HP-UX 11.0 to bring it from 1 GB to 3 GB. How can I tell is the upgrade is successful and that all the modules are recognized? Is there anything I need to watch for during the upgrade?
should work...

Re: Adding RAM to L1000

Hi,

Once the system has booted after the upgrade you can check the ram modules sizes and all using cstm,

echo 'selclass qualifier memory;info;wait;infolog' |cstm > /tmp/meminfo.txt

more /tmp/meminfo.txt

Hope this helps.

Hi,

Try this command:
#echo "selclass qualifier memory;info;wait;infolog"|cstm

Re: Adding RAM to L1000

You can just check the last lines of the dmesg output for the amount of memory or ou can use this little script to check :

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

Hi,

after boot up launch

REAL_MEM=`echo 'phys_mem_pages/D '| adb -k /stand/vmunix /dev/kmem | tail -1 | awk '{ print $2/256}'`
echo $REAL_MEM

or (if system has STM tools)

# mstm

and select memory component ---> information ---> run

Best regards,
Ettore

Re: Adding RAM to L1000

Houston, we have a problem. Any suggestions? These modules are supposed to be 512 MB each, but the new ones appear to be 256 MB each:

Basic Memory Description

Module Type: MEMORY
Total Configured Memory : 2048 MB
Page Size: 4096 Bytes

Memory interleaving is supported on this machine and is ON.

Memory Board Inventory

DIMM Slot Size (MB)
--------- ---------
0a 256
2a 512
1a 256
0b 256
2b 512
1b 256
--------- ---------
System Total (MB): 2048


should work...

Hi,

If cstm is reporting the size of the modules as 256MB, then they are 256. Check with your vendor.

Hope this helps.

Re: Adding RAM to L1000

Hi Ron,

DIMMs are added in pairs. A memory module would consist of 2 DIMMs. So in this case they gave you 512MB modules composed of 2 256MB DIMMS.

Be advised that L1000 can only use the first 4 pairs of DIMM slots 0a/b through 3a/b.
So you better order a 1GB memory module (2 512MB DIMMs) to reach 3GB.

Rgds,
Jeff

Re: Adding RAM to L1000

Actually, the new modules in 2a and 2b look good, now that I take another look.

The modules in 3a and 3b do not appear to be recognized. They must be bad. Bummer.
should work...
