Cause

The DMP Native Support feature is not supported with EFI bootloader.

Solution

This limitation is not addressed in the current Release Notes(InfoScale 7.4), but it is to be included in the next GA Release Notes.

In case dmp_native_support is set "on" inappropriately and it couldn't be reset back to "off". The workaround below is to disable it manually.
