Q) Where did the Optane modules come from? Q) Are the Optane modules new or used? If they were installed in another system, we may need to factory reset them.
The first task is to resolve the "Non-functional" status. This means:
· Non-functional: The PMem module is detected and manageable, though some commands
and capabilities may be limited. The PMem module has limited communication or
another error preventing complete functionality. Common causes include:
· DDRT memory interface training failure
· Expected region mapping to SPA range unable to be found
I'll break down the investigation into sub-sections.
Please ensure the Optane Modules were sourced from a known supplier or originate from a good source. If not, this could be challenging to restore their functionality.
If the modules were originally installed in another host, or hosts, a factory reset may be required.
The Intel Optane Modules are Apache Pass (Optane 100). These modules are supported only by the Intel Xeon Cascade Lake (aka 2nd Generation Intel® Xeon® Scalable Processors). I can't determine what CPUs you have in this system as the BIOS is returning an unknown ID:

The Optane 100 modules were intended to be used with ipmctl version 1.x.x. Optane 200 with ipmctl version 2.x.x, and Optane 300 with ipmctl version 3.x.x. You are using 3.x.x, which may not fully support the 1st generation modules. Try ipmctl version 1.x.x to see if this improves your manageability of the modules.
Look in the BIOS and you should find one or more sub-menus under 'Advanced -> Memory' that allow you to correctly configure the platform in either Memory Mode or App Direct. Your OEM/BIOS vendor determines the exact location, so please take a look at their BIOS manual. This is orthogonal to ipmctl
and should be used as the first approach. You'll find much of the same functionality that ipmctl provides in the BIOS, so I recommend you use this interface.
Some OEMs distributed ipmctl in the UEFI also.

@sscargal Thanks.

CPU is Cascade Lake, the CPUID is 050655h in the CPU-Z. And only one cpu is used in the dual cpu motherboards, does it matter?

ipmctl
I have try ipmctl version 1.x.x and 2.x.x before, it also failed to use in Non-functional status. Then I will try ipmctl-01.00.00.3072 and ipmctl-01.00.00.3547 again.
BIOS Support
In the BIOS manual, it show the Optane Modules is supported. The "CurrentVolatileMode=1LM" shows in the file "ipmctlshow-system” of the pmemchk-log.zip, and how can I set it to 2LM? I want to use them in MemoryMode, but it is in Non-functional status.
Thanks for the background info, it helps.
Given the PMem modules were previously installed in another host, this could be one reason for the current problems. The configuration of the Regions and interleaving is stored on the PMem in the Platform Config Data (PCD), and the BIOS tries to reconstruct this during POST. In the pmemchk output, the ipmctl tool is core dumping when trying to collect this information, so I can't see how many modules should be part of the interleave set. If you don't put all the PMem modules back in the same slots with their interleave friends, the memory training will fail and result in 'Non-Functional' state. Given you don't know how many PMem modules were installed per socket, I recommend trying to Factory Reset them.
The "CurrentVolatileMode=1LM" shows in the file "ipmctlshow-system” of the pmemchk-log.zip, and how can I set it to 2LM?
I found 3 BIOS manuals under the "Config and Deploy" for your server documentation. Specifically, the H3C Servers Purley Platform Text-Mode BIOS User Guide has what you need in the "Intel(R) Optane(TM) DC Persistent Memory Configuration submenu" on Page 86.
I see a 'Secure Erase' option in the Security menu (Page 101). You can try that to see if the DIMMs will Factory Reset.
Page 103 shows the 'Regions submenu screen' where you can 'Delete Goal' and 'Create Goal'. You want to create a new goal for 'Memory Mode (2LM)' to switch from the current AppDirect mode. I don't see any staged goals, so the 'Delete Goal' option may not be visible or may not do anything.
Thanks for the follow up Steve.
I would also think a secure erase/factory reset would be the thing to try.
OK,I will reboot into the bios to check the possibility of Secure Erase/Factory Reset.
@jlin127 - Have you been able to get your Modules working? if so please leave a comment of what fixed your situation and close this thread.
@StevenPontsler Sorry, it has some taskes running in the server now and it will still take more than three days. I will return the report as soon as possible after trying Factory Reset.
I am trying to two AEP memories on a H3C R4700 G3 platform, but it can't be used. All reports of pmemchk is attathed.

Then, I try to upgrade AEP Firmware. It also fail.
