Hi Jeremy,
The T5140/T5240 only support 1.5V ECC FB-DIMMs. If the system detects
a DIMM that:
Is not FB-DIMM (e.g., standard DDR2 ecc),
Has incorrect voltage (e.g., 1.8V),
Is not recognized due to firmware mismatch or unsupported FRU part
number. Should match Oracle/Sun FRU part number(s) exactly!
*DIMMs in a CMP branch must be identical in capacity and FRU.
…otherwise, it will throw a fault like:
Code
DIMM in slot X must be FB-DIMM
This is a hard fault, and the system will disable the DIMM.
Try clearing all system faults, using ILOM cli, specially those that
are memory related. Also note, putting in dimms in an incorrect or
mismatch order may also cause issues. You will have to try different
memory combinations and clearing faults each time (if unsuccessful). I
had something similar happen on my t5140 years ago, but can't say it
will resolve your problem (especially if you have bad hardware
(motherboard, dimms, incorrect FRU for dimms, etc).
Try this:
To clear memory faults on a Sun SPARC Enterprise T5140/T5240, use the
ILOM (Integrated Lights Out Manager) interface.
*1) See this: Also remember to avoid static electricity and ground
yourself before touching anything within the motherboard.
https://docs.oracle.com/cd/E19712-01/E21412-01/z40000741389175.html
2) Access the ILOM CLI Connect via serial console or SSH to the
service processor. You should see the -> prompt.
-> show /SYS
-> show faulty
#This should list all currently faulted components.
Run the Clear Fault Command Use the following syntax:
-> set /SYS/component clear_fault_action=true
#Replace /SYS/component with the actual faulted component path. For
example:
-> set /SYS/MB/MEM0 clear_fault_action=true
Note:
DIMMs are labeled like:
/SYS/MB/MEM0
/SYS/MB/MEM1
etc.
3) Verify Faults Are Cleared Run:
-> show /SYS
-> show faulty
4) Make sure the system is not in diagnostic mode, unless you're
actively troubleshooting:
-> set /SYS keyswitch_state=normal
Regards,
Tony

Jeremy,
I'm unsure if this helps on FBDIMMs, but you could try reseating the
CPU and cleaning (compressed air) of the CPU socket & affected memory
module socket.
I have had success on "weird" memory errors on SD-RAM & DDR Systems
in the past by reseating the CPU.
FB-Dimm is a bit different, though, as the modules are on a serial
bus-like structure iirc, so I'm unsure if a single module on a
channel can be affected and others fine if the CPU connection is the
culprit...
Also, if the system has pluggable VRMs for CPUs and Memory, try
swapping them left/right and see if the error follows.
Greetings,
Robin

Adrian,
So, I was able to pick up some replacement RAM. Doesn't Seem to
matter what modules I have where.
Sometimes I get /SYS/MB/CMP0/BR1/CH0/D0 failed. I've tried moving
modules and it's still this location.
Other times I get a bunch of errors on multiple locations:

These errors aren't accurate. And it seems to be all the modules on
CPU0.
If I power cycle the system I can occasionally get it to boot. I've
been able to get Solaris 11.3 installed and I've booted to it a few
times.
Also, with the latest build of Debian I was able to complete the
install but when it rebooted it still went to Solaris. So I shut it
down planning to boot the other disk in OpenBoot but I haven't been
able to get it to come back up since.
I'm thinking I may have a more serious issue than just memory
modules. OR I have a LOT of bad modules.
I originally had 8 x 4GB modules and I now have 8 x 8GB modules. But
I have the same behaviour regardless which modules are installed and
in what slots. I don't have a mezzanine card installed. This is just
on the motherboard.

It's not 100% clear to me from the logs what could be the source
of the problem
but since error comes from the "cpumem-diagnosis" diagnostic
engine, I would just
try replacing memory modules if you have the possibility.
If you don't have any replacement modules available, I would just
suggest removing
two of the modules (if there are enough) and then booting Solaris
again. Cycle
through all memory modules until the error is gone.
PS: We can continue the discussion on this list, even hardware
failures are on topic.
