Issue:

Running ipmctl show -memoryresources returns an error similar to the following:

# ipmctl show -memoryresources

Error: GetMemoryResourcesInfo Failed

Applies To:

  • Linux & Microsoft Windows
  • Intel Optane Persistent Memory
  • ipmctl utility

Cause:

The Platform Configuration Data (PCD) is invalid or has been erased using a previously executed ipmctl delete -dimm -pcd command or the system has new persistent memory modules that have not been initialized yet.

A module with an empty PCD will show information similar to the following. This shows an example of PCD of DIMM ID 0x0001. To review the PCD for all modules in the system use ipmctl show -dimm -pcd.

# ipmctl show -dimm 0x0001 -pcd

Solution:

Recreate the configuration. For example, the following creates an interleaved set of persistent memory modules in an AppDirect mode for each CPU socket. Read the ipmctl-create-goal(1) man page or the provisioning documentation for more information on the different configuration options.

# ipmctl create -goal persistentmemorytype=appdirect

The following configuration will be applied:

A reboot is required to process new memory allocation goals.

Reboot the host for the changes to take effect:

$ sudo systemctl reboot

After the host reboots, verify the ipmctl show -memoryresources command works as expected, eg:

# ipmctl show -memoryresources
