A director E_Port segmented because no director in the fabric is capable of becoming

the principal switch.

1. Notify the customer the director will set offline. Ensure the system administrator

quiesces Fibre Channel frame traffic through the director and sets attached devices

offline.

2. Set the director offline (Set Offline State on page 3–44).

3. At the Hardware View or Port Card View for the director, choose Configure >

Operating Parameters > Switch Parameters. The Configure Switch

Parameters dialog box displays.

4. At the Switch Priority field, select a switch priority (Principal, Never Principal,

or Default). The switch priority value designates the fabric’s principal switch. The

principal switch is assigned a priority of 1 and controls the allocation and

distribution of domain IDs for all fabric directors and switches (including itself).

Principal is the highest priority setting, Default is the next highest, and Never

Principal is the lowest priority setting. The setting Never Principal means that the

switch is incapable of becoming a principal switch. If all switches are set to

Principal or Default, the switch with the highest priority and the lowest WWN

becomes the principal switch.

At least one switch in a multiswitch fabric must be set as Principal or Default. If

all switches are set to Never Principal, all ISLs segment and the message “No

Principal Switch” displays in the Reason field of the Port Properties

dialog box.
