Zusammenfassung:A method and data processing device for enabling a write operation to track meta-data changes during a hardware fault in an information handling system (IHS). The method includes generating an indexing map to track memory space attributes of a persistent memory device. The method includes generating a subsequent indexing map that is a duplicate of a first indexing map. The method includes communicatively linking each of the indexing maps. The method includes distributing a subsequent indexing map to one or more memory devices. In response to detection of an update to meta-data associated during a hardware fault, the method includes identifying an indexing map that is stored on a writeable memory device. In response to detection of the hardware fault the method includes writing memory space attributes to the writeable indexing map. The method includes synchronizing a master indexing map to each other indexing map to coordinate changes to the memory space attributes.
