Preferred
NOTE: 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 Products in a SAN Environment —
Planning Manual 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).
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 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.
CAUTION: If a switch with a duplicate domain ID exists in the fabric, both switches'
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 switch is in a
multiswitch fabric. The default state is disabled.
