NOTE: 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 appears in the

option. If a check mark displays, the option is enabled.
