fabricPrincipal

Sets the principal switch selection mode.
SYNOPSIS
fabricprincipal --help | -h
fabricprincipal [--show | -q]
fabricprincipal --enable
[ -priority | -p priority]
[-force | -f ]
fabricprincipal --disable
fabricprincipal [-f] mode
DESCRIPTION
Use this command to set principal switch selection mode for a switch and to set priorities for principal
switch selection.
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 is granted this status.
When dealing with large 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 cluster of switches
should be interconnected first, followed by additional switches to enlarge the fabric.
NOTES
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for
details.

Displays the command usage.
Displays the current mode setting and principal switch selection priority. This
operand is optional; if not specified, fabricPrincipal displays the same data as
with the --show option.
Displays principal mode only (enabled or disabled). This is a legacy command
option that does not display the priority settings.
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.
