Fabric Binding; Rerouting Delay; Domain Rscns; Insistent Domain Identification (Id) - HP StorageWorks 2/140 - Director Switch Product Manager Manual

Optional Features
shorter path may arrive ahead of older frames still in route over the older path. If
Rerouting Delay is enabled, traffic ceases in the fabric for the time specified in the
E_D_TOV field of the Configure Fabric Parameters dialog box (Configure menu).
This delay enables frames sent on the old path to exit to their destination before new
frames begin traversing the new path.
If Enterprise Fabric Mode is enabled, this 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
Configure menu in the Product 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 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
Configure menu in the Product 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, then 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 will
disable Enterprise Fabric Mode and Fabric Binding.
