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. A fabric 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
To change this value, you must first set the Switch offline. Choose Set Online State
from the Maintenance menu to display the Set Online State dialog box, then click
the Set Offline button. Be sure to set the Switch back online after you change this
value.
Use this field to set the 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 SAN high availability planning guide
for
details.
