How to tell the number of memory slots available?

[Ben_40]

Using cstm I can determine the number and type of memory boards installed, but how do I determine whether there are free slots available?

[Bill Hassell]

Without opening up the machine and looking at the RAM slots, the only way would be to run the STM diagnostics. These are located on your SupportPlus CDROM. Since you did not provide an operating system rev or model number of your computer, I can't be more specific.

In this particular instance, I need to know the slots on a D250 box running 10.20. However, I look after G/K/N/T boxes running both 10.20 and 11.00 so if there is a 'generic' method of finding out, I'd love to know that as well. I did use the STM diagnostics, but I was unsure how to interpret some of the data.

Did you run memory infomation tool in cstm?

Let 32 be hardware path for the memory installed.
# echo "sel path 32;info;wait;il" | cstm

You can use ODE from your support disk to do a memory map. This will tell you what is installed, where, and what type. It will also tell you what is open.

Likely you can determine from the firmware
boot menu. eg
Information Menu: Enter command > sc

The stm tool can be of help in this situation. You may want to run xstm as well to give a graphic representation of the system guts.

I have just been looking at xstm on my K460. If you open up xstm, go to memory and select it (click once) and then right click and select Information, then it will give a fairly extensive log of information. One of the things it gives is a Memory Board Inventory which tells you which slots in your carrier(s) have memory and what size it is. It does not tell you which slots are free. You could figure this information out if you know the total number of memory slots available for each machine type though.

Here is a sample of the Memory Board Inventory:
