  "definition": "The NVMe LBA Status Information log identifies namespace ranges that warrant further examination for potentially unrecoverable logical blocks.",
  "note": "Log 0Eh has controller scope, with elements for attached namespaces. Its range descriptors and recommended action (RATYPE) guide subsequent Get LBA Status commands; they are not those commands' returned status descriptors. [lba-log12]\n\nReading with RAE=1 freezes this log until a read with RAE=0 clears the outstanding alert, restarts its report interval and permits updates. This snapshot rule is specific to this log, not a universal property of RAE. [lba-log12]\n\nFor RATYPE=10h, acknowledgement suppresses the same namespace element unless another component failure may have created additional untracked LBAs. Retain the guidance before acknowledgement; clearing an alert does not repair data. [lba-log12]\n\nSupport is optional; check OACS.GLSS for the error-oriented capability rather than inferring support from allocation reporting alone. [lba-log12]\n\nCompare the generation counter in the RAE=0 acknowledgement header with the original capture. A mismatch indicates newer log data and permits rereading without waiting for the usual poll interval; it is not evidence of completed recovery. [lba-log12]",
