Suppress Rscn's On Zone Set Activations; Insistent Domain Identification (Id) - HP Surestore 64 - Director Switch User Manual

Optional Features
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 director or switch is offline. In this case, disabling
Domain RSCNs also disables Enterprise Fabric Mode.

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.

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 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 director or switch is offline. If the director or switch is online, disabling
Insistent Domain ID will disable Enterprise Fabric Mode and Fabric Binding.
