Optional Features Rerouting Delay Rerouting Delay is a parameter in the Configure Switch Parameters dialog box, available from the Configure menu in the Product Manager application. Rerouting Delay ensures that frames are delivered through the fabric in order to their destination. If there is a change to the fabric topology that creates a new path (for example, a new switch is added to the fabric), frames may be routed over this new path if the paths hop count is less than a previous path with a minimum hop count. This rerouting 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 (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, 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 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 (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, 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. 188 High Availability Fabric Manager User Guide

High Availability Fabric Manager User Guide

Rerouting Delay

Rerouting Delay is a parameter in the

Configure Switch Parameters

dialog box,

available from the

Configure

menu in the Product Manager application.

Rerouting Delay ensures that frames are delivered through the fabric in order to

their destination.

If there is a change to the fabric topology that creates a new path (for example, a

new switch is added to the fabric), frames may be routed over this new path if the

paths hop count is less than a previous path with a minimum hop count. This

rerouting 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 (

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, 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

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 (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, 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.
