This read-only Counter counts Login Response PDUs transmitted by this target that were not counted by any of the other more specific login-failure counters in the row. An admin treats increases here as a catch-all warning sign of login problems that don't fit the named categories (redirect, authorization, authentication, negotiation), prompting deeper packet-level investigation. For example, a rise in this counter with no corresponding rise in cpqiScsiTgtLoginAuthenticateFails might point an admin toward an unusual or malformed login sequence from a non-compliant initiator.
