Domain Rscns; Insistent Domain Identification (Id) - HP 316095-B21 - StorageWorks Edge Switch 2/24 User Manual

Optional Features
If Enterprise Fabric Mode is enabled, this option is automatically enabled and
cannot be disabled unless the switch is offline. In this case, disabling Rerouting
Delay also disables Enterprise Fabric Mode.

Domain RSCNs

This is a parameter in the Configure Switch Parameters dialog box, available
from Configure menu in the Product Manager application. 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.
If Enterprise Fabric Mode is enabled, this parameter is automatically enabled and
cannot be disabled unless the switch is offline. In this case, disabling Domain
RSCNs also disables Enterprise Fabric Mode.

Insistent Domain Identification (ID)

This is a parameter in the Configure Switch Parameters dialog box, available
from Configure menu in the Product Manager application. Enabling this option
sets the domain ID configured in the Preferred Domain ID field in the Configure
Switch Parameters dialog box as the active domain identification when the fabric
initializes. A static and unique domain identification is required by the Fabric
Binding feature because the feature's Fabric Membership list identifies switches
by WWN and Domain ID. If a duplicate preferred domain ID is used, then
insisted, warnings occur when Directors and Edge Switches are added to a Fabric
Membership List.
If Fabric Binding or Enterprise Fabric Mode is enabled, this option is
automatically enabled and cannot be disabled unless these options are disabled
when the switch is offline. If the switch is online, disabling Insistent Domain ID
will disable Enterprise Fabric Mode and Fabric Binding.
