The term “unaffiliated” is used because the error cannot be associated (or affiliated) with a specific QP or EEC. How the error is handled is defined by the error type:
Local Catastrophic Error. The error cannot be associated with any resource. The behavior of the HCA and/or its driver are indeterminate.
Port Error. This error is reported when a link becomes unavailable. It is generated when the link associated with an HCA port transitions from the available to the unavailable state. Refer to “Link State Machine” on page 602 for a detailed description of the possible port states:
3.138.138.30
