2 fabricPrincipal EXAMPLES --enable Enables principal switch selection. The following operands are optional. If you do not provide a priority value, the system assigns the default of 0x01 or generates a value based on the switch state. -priority | -p priority Sets the principal selection priority of the switch. The specified priority value is used in the principal switch selection protocol when the fabric rebuilds. Not all of these values can be assigned. 0x00 Reserved. This value cannot be assigned. 0x01 Highest priority. This is a user-defined value 0x02 Switch was principal prior to sending or receiving a build fabric (BF) request. This value is generated by the switch to initiate a fabric reconfiguration. This value should not be assigned. 0x3 - 0xFE Priority value range. Choose a value in this range to indicate priority. Higher numbers mean lower priority. 0xFF Switch is not capable of acting as a principal switch. This is a user-defined value. Use --enable with a new priority to revert to this condition. -force | -f Forces a fabric rebuild. This option is required when enabling principal switch mode. This option is not valid with the --disable command. --disable Disables principal switch selection. This command resets the priority to the default value 0xFE. [-f] mode Sets the principal switch mode. Specify 1 to enable principal switch mode. Specify 0 to disable principal switch mode. Optionally, use the -f operand to force a fabric rebuild. Mode changes take effect when the fabric rebuilds. This operand is optional. To enable a high fabric principal priority setting: switch:admin> fabricprincipal --enable -p 0xff -f Principal Selection Mode enabled (Activate in \ next fabric rebuild) To disable the principal mode selection: switch:admin> fabricprincipal --disable Principal Selection Mode disabled To display the current mode setting: switch:admin> fabricprincipal -q Principal Selection Mode: Enable To disable the mode setting: switch:admin> fabricprincipal 0 Principal Selection Mode disabled 274 Fabric OS Command Reference 53-1002746-01
