Fabricprincipal - Brocade Communications Systems A7533A - Brocade 4Gb SAN Switch Base Command Reference Manual

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.
Note 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.

Fabric OS Command Reference

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.
Disables principal switch selection. This command resets the priority to the
default value 0xfe.
Enables principal switch selection. The following operands are supported with
the --enable command:
-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. The
valid range of priorities are 0x01 (low priority) to 0xff (high priority). This
operand is optional and valid only with the --enable command. When the
priority is not specified, the priority defaults to 0x01.
-force|-f Forces a fabric rebuild. This option is required when enabling principal switch
mode. This option is not valid with the --disable command.
Disables principal switch selection. This command resets the priority to the
default value 0xfe.
