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

Re: Adding RAM to L1000

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...

Re: Adding RAM to L1000

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.

Re: Adding RAM to L1000

OK - I see.
Also I believe that HP recommends the larger DIMM modules be installed in the lower slots.
So you may want to shift those around so the 512 DIMMs are in 0a/b & 1a/b & the 256 DIMMs in 2a/b & 3a/b

Jeff: Ah ha! Thanks! That makes sense; I'll give it a go. I had never read that anywhere.

Re: Adding RAM to L1000

hi,

the recommendation of putting the largest modules in the lowest slots is for performance reasons. The modules should be visible and working if inserted in the opposite manner.

You can view the installed memory from the ISL (INF), you do not have to boot your system completely.

good luck,
Thierry.

Re: Adding RAM to L1000

Note that the best way to check for proper addition of memory is via the BCH (Boot Console Handler) INfo MEmory command. It will give you good details on the memory congfiguration that System Selftest has configured - as well as point out any errors it encountered. The next best way is via the "MAPPER" utility (ODE Utility run at ISL). Also note that the L1000 is firmware limited to 4GB of memory max (PDC release < 40.19) or 8GB memory max (PDC 40.19 +).
