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 multi-switch 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.

5. Set the director online (“Set Online State” on page 205).

Did the switch priority change solve the problem and did both directors join

through the ISL to form a fabric?

NO YES
