Enabling the Enterprise Fabric Mode 5 Domain RSCNs and the Enterprise Fabric Mode Insistent Domain Identification (ID) and the Enterprise Fabric Mode switch is offline. In this case, disabling Rerouting Delay also disables Enterprise Fabric Mode. For information about configuring and enabling Rerouting Delay, see Configuring Switch Parameters on page 3-11. Domain register for state change notifications (domain RSCNs) are sent between end devices in a fabric to provide additional connection information to host bus adapters (HBA) and storage devices. As an example, this information might be that a logical path has been broken because of a physical event, such as a fiber optic cable being disconnected from a port. If Enterprise Fabric Mode is enabled, Domain RSCNs are automatically enabled and cannot be disabled unless the director or switch is offline. In this case, disabling Domain RSCNs also disables Enterprise Fabric Mode. For information about enabling Domain RSCNs, see Configuring Switch Parameters on page 3-11. If enabled, Insistent Domain ID specifies that the preferred domain ID configured for the product will be the product's active domain identification when the fabric initializes. For information about configuring the preferred domain ID, see Configuring Switch Parameters on page 3-11. A static and unique domain ID is required by the Fabric Binding feature because the feature's FBML identifies switches by WWN and domain ID. If a duplicate preferred domain ID is used, then made insistent, warnings display when directors and switches are added to an FBML. If Fabric Binding or Enterprise Fabric Mode is enabled, Insistent Domain ID is automatically enabled and cannot be disabled unless the director or switch is offline. In this case, disabling Insistent Domain ID disables Enterprise Fabric Mode and Fabric Binding. For information about configuring the domain ID and Insistent Domain ID, see Configuring Switch Parameters on page 3-11. 5-24 EFCM Basic User Manual
