Dear all,

I'm trying to find out howto disable a memory bank on a systemboard
using DR (I want to avoid using the blacklist because that requires a
reboot).
My first question is, how does the OS writes to his memory?

SB00
---------------------------------
CPU0 CPU2 |
        Bank 0 Bank 2 |
        DIM0 DIM0 |
        DIM1 DIM1 |
                                                                |
CPU1 CPU3 |
        Bank 1 Bank 3 |
        DIM0 DIM0 |
        DIM1 DIM1 |
---------------------------------

How does the kernel actually writes to his memory keeping in mind were
speaking about a board which does not contain the permanent memory.
If I'm not mistaken only memory can be disabled only by pair ( 0 and 1
or 2 and 3).

Does it also write acros to it's dims (to 0 and 2 or 1 and 3)?

What's the cfgadm syntax to disable a DIM/Bank on a 15K

thx

Thanks in advance.
