Switch parameters

Configure the following parameters as required by your fabric.

Domain ID

The domain identification is a value from 1 through 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: To change this value, you must first set the switch offline. For instructions, see ”Set the switch

offline” on page 44.

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.

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).

When a check mark is displayed, 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 High Availability Fabric Manager (HAFM) 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.
