We have a rx8640 server that has 4 dimms deconfigured, after a couple of panics/mcas.
DIMM Location Size(MB) State Serial Num Part Num
-------------------- -------- ------- ---------------- ------------------
Cab 0 Cell 3 DIMM 0A 2048 Deconf PR A9846-60301
Cab 0 Cell 3 DIMM 0B 2048 Deconf PR A9846-60301
Cab 0 Cell 3 DIMM 1A 2048 Config PR A9846-60301
Cab 0 Cell 3 DIMM 1B 2048 Config PR A9846-60301
Cab 0 Cell 3 DIMM 2A 2048 Config PR A9846-60301
Cab 0 Cell 3 DIMM 2B 2048 Config PR A9846-60301
Cab 0 Cell 3 DIMM 3A 2048 Deconf PR A9846-60301
Cab 0 Cell 3 DIMM 3B 2048 Deconf PR A9846-60301
Cab 0 Cell 3 DIMM 4A 2048 Config PR A9846-60301
Cab 0 Cell 3 DIMM 4B 2048 Config PR A9846-60301
Cab 0 Cell 3 DIMM 5A 2048 Config PR A9846-60301
Cab 0 Cell 3 DIMM 5B 2048 Config PR A9846-60301
Cab 0 Cell 3 DIMM 6A ---- ---- ---- ----
We are going to replace the deconfigured dimms, my question is, is there a way to configure them from efi(ala cpuconfig) once we have changed them, or will they be configured by the system(if there are no errors) on next reboot?
should we also clear the pdt table just in case?
Thanks!

Re: Memory deconf in rx8640
Shell> info mem
You will see a column "hardware deconfigured" and a "software deconfigured".
This means a hardware failure on a single DIMM will probably deconfigure other DIMMs as well.
Maybe you get the same result online:
# echo "selclass qualifier memory;info;wait;infolog" | /usr/sbin/cstm
Please try this.
Hope this helps!
Regards
Torsten.

Re: Memory deconf in rx8640
But there seems to be no mem config command in EFI, similar to cpuconfig for the cpus.
