fabricprincipal fabricprincipal Set the Principal Switch Selection mode. Synopsis fabricprincipal [-fhq][ 1 | 0 ] Availability All users can display current setting. Admin can modify current setting. Release V4.1.x Description Use this command to set Principal Switch Selection Mode for the switch. The implementation of the fabricprincipal command is based solely on mechanisms specified in the Fibre Channel standards. These mechanisms provide a preference for a switch requesting to be the principal switch in a fabric, but they do not provide an absolute guarantee that a switch requesting to be the principal switch will actually achieve this status. When dealing with larger fabrics, the selection of the principal switch is less deterministic. In these cases, to help ensure that the desired switch is selected as the principal switch, a small selection of switches should be connected together first, followed by the addition of the rest of the fabric. Operands This command has the following operands: -f Specify the -f option to force a fabric rebuild. This option is required with when enabling principal switch mode. -h Specify the -h option to display out command usage summary. -q Specify the -q option to display the current mode state.
