The persistent memory drives lose persistency

Symptom

A persistent memory drive can potentially lose its ability to persist data after it has booted to the OS. When this event occurs, the server notifies the OS. The handling of this event is by the OS and version dependent.

Solution 1
Cause

The Persistent Memory Address Range Scrub error threshold is exceeded.

Action
Using UEFI System Utilities, reinitialize the backup storage devices.

For more information, see the UEFI System Utilities user guide for your product on the Hewlett Packard Enterprise website (http://www.hpe.com/info/uefi/docs).

Solution 2
Cause

The backup power source capacity no longer supports the backup operation.

Action
  1. Review the IML for messages indicating the error with a backup power source.
  2. Replace the backup power source device indicated in the IML.

    For more information, see the server maintenance and service guide.

Solution 3
Cause

An NVDIMM controller error occurred at runtime.

Action
  1. Review the IML for messages indicating the NVDIMM controller error.
  2. Perform the steps indicated in the IML.
