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.

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.
