ABSTRACT:
Administering correlated error logs in a computer system having a system controller and one or more redundant node controllers including providing by the system controller to a redundant node controller a unique identifier for error logs; detecting by the system controller a communications failure between the system controller and the redundant node controller; in response to detecting the communications failure, generating by the system controller a system controller error log for the communications failure including the unique identifier; detecting by the redundant node controller the communications failure between the system controller and the redundant node controller; and in response to detecting the communications failure, generating by the redundant node controller a redundant node controller error log for the communications failure including the unique identifier.
