Domain ID disables Enterprise Fabric Mode and Fabric Binding.

Page 130 highlights

Enabling the Enterprise Fabric Mode 5 Domain RSCNs and the Enterprise Fabric Mode Insistent Domain Identification (ID) and the Enterprise Fabric Mode switch is offline. In this case, disabling Rerouting Delay also disables Enterprise Fabric Mode. For information about configuring and enabling Rerouting Delay, see Configuring Switch Parameters on page 3-11. 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, Domain RSCNs are automatically enabled and cannot be disabled unless the director or switch is offline. In this case, disabling Domain RSCNs also disables Enterprise Fabric Mode. For information about enabling Domain RSCNs, see Configuring Switch Parameters on page 3-11. If enabled, Insistent Domain ID specifies that the preferred domain ID configured for the product will be the product's active domain identification when the fabric initializes. For information about configuring the preferred domain ID, see Configuring Switch Parameters on page 3-11. A static and unique domain ID is required by the Fabric Binding feature because the feature's FBML identifies switches by WWN and domain ID. If a duplicate preferred domain ID is used, then made insistent, warnings display when directors and switches are added to an FBML. If Fabric Binding or Enterprise Fabric Mode is enabled, Insistent Domain ID is automatically enabled and cannot be disabled unless the director or switch is offline. In this case, disabling Insistent Domain ID disables Enterprise Fabric Mode and Fabric Binding. For information about configuring the domain ID and Insistent Domain ID, see Configuring Switch Parameters on page 3-11. 5-24 EFCM Basic User Manual

EFCM Basic User Manual
Enabling the Enterprise Fabric Mode
switch is offline. In this case, disabling Rerouting Delay also disables
Enterprise Fabric Mode. For information about configuring and
enabling Rerouting Delay, see
Configuring Switch Parameters
on
page 3-11.
Domain RSCNs and
the Enterprise Fabric
Mode
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, Domain RSCNs are
automatically enabled and cannot be disabled unless the director or
switch is offline. In this case, disabling Domain RSCNs also disables
Enterprise Fabric Mode. For information about enabling Domain
RSCNs, see
Configuring Switch Parameters
on page 3-11.
Insistent Domain
Identification (ID) and
the Enterprise Fabric
Mode
If enabled, Insistent Domain ID specifies that the preferred domain
ID configured for the product will be the product’s active domain
identification when the fabric initializes. For information about
configuring the preferred domain ID, see
Configuring Switch
Parameters
on page 3-11.
A static and unique domain ID is required by the Fabric Binding
feature because the feature's FBML identifies switches by WWN and
domain ID. If a duplicate preferred domain ID is used, then made
insistent, warnings display when directors and switches are added to
an FBML.
If Fabric Binding or Enterprise Fabric Mode is enabled, Insistent
Domain ID is automatically enabled and cannot be disabled unless
the director or switch is offline. In this case, disabling Insistent
Domain ID disables Enterprise Fabric Mode and Fabric Binding. For
information about configuring the domain ID and Insistent Domain
ID, see
Configuring Switch Parameters
on page 3-11.
