Installing and Configuring the Director
72
Director 2/140 Installation Guide
Use this field to set a unique domain ID for the director. The default value is 1. Set
a value between 1 and 31. When a director comes online with a preferred ID, it
requests an ID from the fabric’s principal director (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. If the requested domain ID is
already allocated, an unused domain ID is assigned. Note that you must set the
director offline before you can change to the preferred domain ID.
The preferred domain ID must be unique for each director and switch in a fabric.
If two switches or directors have the same preferred domain ID, the E_Ports
segment, causing the fabric to segment.
For more information on domain ID, refer to the section on domain ID assignment
for multi-switch fabrics in the HP StorageWorks SAN High Availability Planning
Guide for details.
Insistent
This option is not supported unless the SANtegrity Binding feature is installed.
Click the check box to remove or add a check mark. The default state is disabled
(no check mark).
When a check mark displays, the domain ID configured in the Preferred Domain
ID field will become the active domain identification when the fabric initializes.
See the following notes:
■
This option is required if Enterprise Fabric Mode (optional SANtegrity
Binding feature) is enabled.
■
If you enable Insistent Domain while the switch or director is online, the
Preferred Domain ID will change to the current active domain ID if the IDs
are different.
Caution:
If a director with a duplicate domain ID exists in the fabric, both
directors' E_Ports will segment when they try to join.
Rerouting Delay
Placing a check mark in the check box to the left of the Rerouting Delay option
enables rerouting delay. This option is only applicable if the configured director is
in a multi-switch fabric. The default state is enabled.
Enabling the rerouting delay ensures that frames are delivered in order through the
fabric to their destination. If there is a change to the fabric topology that creates a
new path (for example, a new director is added to the fabric), frames may be
