how RAM is split up in differents slots

Hello,

We have some L3000 and L2000 servers and we would like to know how RAM is split up in different slots ? And how many slots are available ?

Someone can help me ?

Thanks,

Re: how RAM is split up in differents slots

Use this to list what you have;

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

I don't think it will show total number of slots though so you may need to look at the product documentation.

Hi Oliva,

to check the quantity and size of the memory modules, you can break the boot process and enter BCH console. Then you enter Information menu and run Memory entry.
You will have full list of memory slots.

Another way is to use stm or xstm directly from HP-UX level.

I'm pretty sure an L2000 and L3000 can hold a total of 16 dimms.

I don't have the product docs here handy. But we have an L2000 here that I looked at knowning all the slots were filled. And that server had 16 dimms. I'm pretty sure the L3000 is the same.

L2000 has 16 memory slots directly on system board.
L3000 (current name rp5470) can have one or two memory carriers, each having 8 memory slots. The memory carriers are connected to system board.

OLIVA,

you best bet is a picture: run the xstm on each system. you must have even memory chips (DIMMs). for example: 1a and 1b.

you can not run with only 1a, this is my point!

so, keep things in a Pair (or even 2 count).

also, if you move things around, make certain, the DIMM size is the same for each balance: 1a and 1b. So, if you order: 512MB DIMMS (these actually come in a pair, of 2 of 256MB). think pairs, and the #slot must have the same sizes for the A and B side.
