Configuring the Director
This may result in frames being delivered to a destination out of order since frames
sent over the new, 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. This delay allows
frames sent on the old path to exit to their destination before new frames begin
traversing the new path.
NOTE: This option is required if Enterprise Fabric Mode (optional SANtegrity binding feature) is
enabled.
Domain RSCNs
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. Consult with your HBA and storage device vendor to
determine if enabling Domain RSCNs will cause problems with your HBA or storage
products. Note that this option is required if Enterprise Fabric Mode (optional
SANtegrity binding feature) is enabled.

All FPM ports will be held
inactive while the director is configured to 2 Gb/sec speed. Do you
want to continue?
