The persistent memory drive is read only

Symptom

A persistent memory drive marked as "read only" usually indicates that the underlying NVDIMM detected is not armed for backup during the boot process.

Solution 1
Cause

Previous backup operation failed.

Action
Check the IML for the cause of the backup failure and perform the recommended action.
Solution 2
Cause

The current restore operation failed.

Action
Check the IML for the cause of the restore failure and perform the recommended action.
Solution 3
Cause

A general Scalable Persistent NVDIMM arming error occurred.

Action
Check the IML for additional errors and perform the recommended action.
Solution 4
Cause

The persistent memory backup power requirements exceed the available backup battery power.

Action
Remove any hardware that was recently added to the server.
Solution 5
Cause

The backup energy source is not sufficiently charged and the charging process was skipped by the user.

Action
Reboot the system and wait for the backup energy source to sufficiently charge.
Solution 6
Cause

The backup energy source is not sufficiently charged and the charging process timed out.

Action
  1. Check the IML for additional backup power source-related messages and perform any recommended actions.
  2. If the issue still exists, replace the backup power source.

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

Solution 7
Cause

The backup power source capacity can no longer support the Scalable Persistent Memory backup operation.

Action
  1. Review the IML for backup power source errors.
  2. Replace the backup power source device indicated by the IML.
