Hard zoning is compatible with legacy zone definitions, including World Wide Name

(WWN) and por t zoning. You can use your existing zones and zone sets without any

changes. There are no changes to the zoning interfaces, so you do not need to modif y

your zone management practice, modify your documentation, or retrain Storage Area

Network (SAN) administrators.

Hard zoning controls access at the ingress port. When a port attempts to send a frame

to a destination outside its zones, the frame is blocked. A Class 2 frame is fabric

rejected, and a Class 3 frame is dropped.

Zoning change RSCN control

Normally, when

a zone set is activated, a fabric format doma in Register State Change

Notification

(RSCN) is sent to all devices in the fabric. With firmware 05.00.00 or later,

you can disable these RSCNs from being sent. This is done using the Suppress RSCNs

on zon e set activations check box on the Configure Switch Parameters dialog box.

This feature

significantly changes the normal behavior of the fabric. Devices will

have no warning when zones change and will not automatically update their zoning

information. The ability to suppress RSCNs is disabled (check box is not selected) by

default. This feature can be configured through HAFM, EWS, and CLI.
