Planning Considerations for Fibre Channel Topologies - Incompatible zoning configurations - Zoning configurations for the two fabric elements are not compatible. For an explanation, refer to "Configuring Zones" on page 133. - Build fabric protocol error - A protocol error is detected during the process of forming the fabric. - No principal switch - No director or switch in the fabric is capable of becoming the principal switch. - No response from attached switch - After a fabric is created, each element in the fabric periodically verifies operation of all attached switches and directors. An ISL segments if a director or switch does not respond to a verification request. - ELP retransmission failure timeout - A director or switch that exhibits a hardware failure or connectivity problem cannot transmit or receive Class F frames. The director or switch did not receive a response to multiple exchange link parameters (ELP) frames, did not receive a fabric login (FLOGI) frame, and cannot join an operational fabric. ■ Fabric services and state change notifications - In a multi-switch fabric, services provided by each director or switch (such as name service, registered state change notifications [RSCNs], and zoning) are provided on a fabric-wide basis. For example, if a fabric-attached device queries a director or switch name server to locate all devices that support a specified protocol, the reply includes all fabric devices that support the protocol that are in the same zone as the requesting device, not just devices attached to the director or switch. RSCNs are transmitted to all registered device N_Ports attached to the fabric if either of the following occur: - A fabric-wide event occurs, such as a director or switch logging in to the fabric, a director or switch logging out of the fabric, or a reconfiguration because of a director, switch, or ISL failure. - A zoning configuration changes.
