Configuring the Director
When a director/switch comes on line with a preferred domain ID, it
requests an ID from the fabric’s principal switch (indicating its
preferred value as part of the request). If the requested domain ID is
not allocated to the fabric, the domain ID is assigned to the requesting
director/switch. If the requested domain ID is already allocated, an
unused domain ID is assigned.
Insistent
This option is supported only if the Enterprise Fabric Extensions feature is
installed, and is required if Enterprise Fabric Mode is enabled. Insistent
Domain IDs do not requrie either of these to be enabled. (Refer to the
Connectrix Manager Version 7.01 User Guide for more information on these
features.)
If this option is enabled (checked), the Preferred Domain ID will
become the active domain identification when the fabric initializes.
Click the check box to remove or add a checkmark. (The default state
is no checkmark.)
The Fabric Binding feature (described in the Connectrix Manager
Version 7.01 User Guide) requires a static and unique domain
identification, because the feature's fabric membership list identifies
switches by WWN and Domain ID.
If a duplicate preferred domain ID is used, and then insisted, warnings occur
when directors/switches are added to a fabric membership list.
Note the following:
◆
If Fabric Binding or Enterprise Fabric Mode is enabled, the
Insistent Domain ID option is enabled automatically.
◆
Disabling the Insistent option while the director is on line disables
both Enterprise Fabric Mode and Fabric Binding. (You can disable
the option while the director is off line without affecting
Enterprise Fabric Mode or Fabric Binding.)
◆
If you enable the Insistent option while the director is on line, the
Preferred Domain ID changes to the current active domain ID if
the IDs are different.
