Configuring the Director 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. Suppress RSCN's 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 check box is selected, 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 checkmark. This option is enabled (check box not selected) by default. In most cases this option should be enabled 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) 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 Gb/sec and at least one port is configured at 2 Gb/sec, an error message displays stating that you cannot modify the director speed. ■ If you set the director data speed to 2 Gb/sec, all installed CTP cards must support 2 Gb/sec data speed or an error message displays stating that you cannot modify the director speed. 122 Director Product Manager User Guide

Configuring the Director
122
Director Product Manager User Guide
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.
Suppress RSCN’s 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
check box
is selected, 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 checkmark.
This option is enabled (check box not selected) by default. In most cases this
option should be enabled 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)
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 Gb/sec and at least one port is configured at 2 Gb/sec, an
error message displays stating that you cannot modify the director speed.
If you set the director data speed to 2 Gb/sec, all installed CTP cards must
support 2 Gb/sec data speed or an error message displays stating that you
cannot modify the director speed.
