If Enterprise Fabric Mode is enabled, the Rerouting Delay option is
automatically enabled and cannot be disabled unless the director or switch is
offline. In this case, disabling Rerouting Delay also disables Enterprise Fabric
Mode.
Domain RSCNs
This is a parameter in the Configure Switch Parameters dialog box, available from
the Configure menu in the Element Manager application. 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 (HBAs)
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, this parameter is automatically enabled and
cannot be disabled unless the director or switch is offline. In this case, disabling
Domain RSCNs also disables Enterprise Fabric Mode.
Insistent Domain Identification (ID)
This is a parameter in the Configure Switch Parameters dialog box, available from
the Configure menu in the Element Manager application. Enabling this option
sets the domain ID configured in the Preferred Domain ID field in the Configure
Switch Parameters dialog box as the active domain identification when the fabric
initializes. A static and unique domain identification is required by the Fabric
Binding feature because the feature's Fabric Membership list identifies switches
by WWN and Domain ID. If a duplicate preferred domain ID is used, and insisted,
warnings occur when directors and switches are added to a Fabric Membership
List.
If Fabric Binding or Enterprise Fabric Mode is enabled, this option is
automatically enabled and cannot be disabled unless these options are disabled
when the director or switch is offline. If the director or switch is online, disabling
Insistent Domain ID disables Enterprise Fabric Mode and Fabric Binding.
