This read-only Counter counts Logout Command PDUs received by this target with any status code other than 0, i.e. non-normal logout reasons. An admin watches for increases here as a sign that initiators are terminating sessions abnormally, which could indicate initiator-side errors or unexpected reboots. For example, a spike in this counter coinciding with a client server crash would help the admin correlate the storage-side symptom with the host-side event.
