Installing and configuring the director70

and storage device vendor to determine if enabling Domain RSCNs will cause problems with your

HBA or storage products.

NOTE: This option is required if Enterprise Fabric Mode (optional SANtegrity Binding feature) is

enabled. The default state is enabled.

Suppress RSCNs on zone set activations

Fabric format domain register for state change notifications (RSCNs) are sent to ports on the switch

following any change to the fabric's active zone set. These changes include activating and

deactivating the zone set, or enabling and disabling the default zone. When the Suppress RSCNs

on Zone Set Activations box is selected, fabric format RSCNs are not sent for zone changes to the

attached devices on the switch. Click the box to remove or add a check mark.

In most cases this it is desirable to enable this option so that attached devices can receive

notification of zoning changes in the fabric. However, some HBAs may log out, then log back into

the fabric when they receive an RSCN, thereby disrupting Fibre Channel traffic. Consult with your

HBA and storage device vendor to determine if disabling this option (and thereby enabling RSCN

transmission) will cause problems with your HBA or storage products. This option is disabled by

default.

Director speed

At the Director Speed box, select 1 Gb/sec or 2 Gb/sec to select the speed of Fibre Channel

operation.

NOTE: Changing the switch speed to 2 Gb/sec with any 1 Gb/sec FPM cards installed causes the

following warning/confirmation message to display: “All FPM ports will be held

inactive while the switch is configured to 2 Gb/sec speed. Do you want

to continue?”

Configuring fabric parameters

Use procedures in this section to set parameters on the director for fabric operation through the

Configure Fabric Parameters dialog box. These parameters are stored in NV-RAM on the director.

1. Verify that the director is set offline. For instructions, see ”Setting the director offline” on

page 66.

CAUTION: Setting the director offline terminates all Fibre Channel connections.

2. Select Configure > Operating Parameters > Fabric Parameters.
