default setting is 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 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 appears in the Reason field of the Port Properties dialog box.
