Configuring the Director
121 Director Element Manager User Guide
Note: This option is required if Enterprise Fabric Mode (optional SANtegrity Binding
feature) is enabled.
Suppress Zoning 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 Zoning RSCNs on zone set activations
check box contains a check, fabric format RSCNs are not sent for zone changes to
the attached devices on the switch. Click the check box to remove or add a check
mark.
This option to suppress RCNs is disabled by default and, in most cases, should be
disabled 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.
Director Speed (Director 2/64 Only)
Note: To change this value, you must first set the director offline. Be sure to set the
director back online after you change this value.
When setting the director speed, consider the following:
■ Configure port speeds individually through the Configure Ports dialog box.
You cannot set a director speed to less than the port speeds. If you set the
director speed to
1 Gig and at least one port is configured at 2 Gig, an
error message displays stating that you cannot modify the director speed.
■ If you set the director data speed to 2 Gig , all installed CTP cards must
support 2 Gb/s data speeds or an error message displays stating that you
cannot modify the director speed.
■ When you change the speed to 2 Gig , all ports on Fibre Channel port
module (FPM) cards go to an inactive state. A warning/confirmation message
also displays, allowing you to continue the operation or cancel. Only universal
port module (UPM) cards allow 1 Gb/s and 2 Gb/s operation.
