4. With the AC power o, install each DCPMM into the target workstation, using the same DIMM slots

as on the source workstation.

5. Reboot the system and check for any POST errors. If the DCPMMs are not installed in the correct DIMM slots

you may see a POST message indicating the correct DIMM slot(s). Note down the correct slots, power o

the workstation, and move the DCPMMs to these DIMM slots.

6. If DCPMM passphrases were set on the source workstation, you will be prompted for the passphrases

for the these DCPMMs on the target workstation. If Transparent Unlock was enabled on the source

workstation, import the passphrase le from the USB stick.

7. The storage volume(s) on the DCPMMs should be seen by the target workstation with all data still present.

It is not necessary to congure the DCPMMs in F10 Setup. The previous conguration will be retained.

DCPMM Status Checks

1. All the following commands can be run from the UEFI Shell command prompt. Those noted cannot be run

from Windows.

2. To create a bootable UEFI Shell USB key use the following steps:

• Download the following le –

https://github.com/tianocore/edk2/blob/master/ShellBinPkg/UeShell/X64/Shell.e

• Rename the le to bootx64.EFI

• Copy the le to a FAT32 formatted USB key in the following directory: \EFI\Boot\

3. Download the SoftPaq that includes the Intel

Optane™ DC Persistent Memory EFI utility (ipmctl.e)

• Extract and copy the contents of the SoftPaq to the bootable UEFI Shell USB key.

4. For Windows, HP provides a SoftPaq that includes the Intel

Optane™ DC Persistent Memory Software utilities

(DCPM_Software.exe) – Download the SoftPaq and install this software.

5. Commands to view conguration:

• ipmctl.e show -memoryresouces

This shows the conguration when in Memory Mode.

• ipmctl.e show -a -region

This shows the AppDirect regions present on the modules.

• ipmctl.e show -a namespace

This shows the AppDirect namespaces present on the modules.

This command does not work in Windows, instead use Get-PmemDisk from an Administrator

PowerShell prompt.

• ipmctl.e show -a -socket

This shows the memory limit of the processor.

6. Commands to check the status of the modules.

• ipmctl.e show -dimm

This shows information about all installed DCPMMs – DimmID, Capacity, HealthState, LockState,

FW Revision.

• ipmctl.e show -sensor

This shows basic health information about all installed DCPMMs.

• ipmctl.e show -topology

This shows the topology of installed DCPMMs and DRAM.

• ipmctl.e show -socket

This shows the memory limit of the installed processor(s).

• ipmctl.e show -memoryresources

This shows information about how the installed DCPMMs are congured.

• Ipmct.e show -sensor ControllerTemperature

This shows the controller temperature of the installed DCPMM.

• Ipmct.e show -sensor MediaTemperature

This shows the media temperature of the installed DCPMM.

Resetting a DCPMM to Factory State

• Ensure DCPMM is in an unfrozen state.

• To reset the DCPMMs to a known/factory state as they came from Intel use the following UEFI command

sequence. This should work regardless of the conguration of the DCPMM. These commands must be run from

an UEFI Shell.

• Commands are as follows:

ipmctl.e delete -force -dimm -pcd LSA

ipmctl.e delete -force -dimm

ipmctl.e create -force -goal MemoryMode=100
