Installing and Configuring the Edge Switch 2/24

Switch Parameters

Configure the following parameters as required by your fabric.

Domain ID

The domain identification is a value between 1 and 31 that provides a unique
identification for the switch in a fabric. An Edge Switch cannot contain the same
domain ID as another switch or their E_Ports will segment when they try to join.
In the Configure Switch Parameters dialog box, a field is provided to enter a
preferred domain ID and a check box is provided to enable this ID as an insistent
domain ID.

Preferred

Note:
State from the Maintenance menu to display the Set Online State dialog box, then click
the button. Be sure to set the switch back online after you change this value.
Use this field to set a unique domain ID for the switch. The default value is 1. Set
a value between 1 and 31. When a switch comes online with a preferred 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 switch. If the requested domain ID is
already allocated, an unused domain ID is assigned. Note that you must set the
switch 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 multiswitch fabrics in the HP StorageWorks High Availability SAN Planning
Guide for details.

Insistent

This option is not supported unless the SANtegrity feature is installed. Click the
check box to remove or add a check mark. The default state is disabled (no check
mark).

To change this value, you must first set the switch offline. Choose Set Online
