Runtime mechanism to correct incomplete namespace in persistent memory

摘要

An Information Handling System (IHS) includes one or more persistent memory devices coupled to a processor and system memory. During runtime, a namespace correction agent monitors the persistent modules whose full physical address space are configured as block mode and/or interleave set namespace. The namespace correction agent identifies an incomplete namespace trigger that is detected by a driver and caused by one of a faulty or missing persistent memory module. In response to identifying the incomplete namespace trigger, the namespace correction agent: access memory details identifying a corresponding faulty or missing persistent module to determine a physical label address corresponding to the incomplete namespace; corrects the physical label address corresponding to the incomplete namespace; and reenumerates the relabeled memory.
