fabricPrincipal

fabricPrincipal
Sets principal switch selection mode.
Synopsis fabricprincipal [-fhq] [mode]
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 achieves 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.
Note The execution of this command is subject to Admin Domain restrictions that may be in place. Refer
to chapter 1, "Understanding Admin Domain Restrictions" and Appendix A, "Command Availability"
for details.
