Fabric OS Command Reference 821

reBoot
2
reBoot
Reboots the control processor (CP).
Synopsis reboot [-f]
Description Use this command to perform a “cold reboot” (power off/restart) of the control processor. This
operation may be disruptive, and the command prompts for confirmation before executing. When
you reboot a switch connected to a fabric, all traffic to and from that switch stops. All Fibre Channel
ports on that switch including E_Ports become inactive until the switch comes back online.
The behavior of this command depends on the platform:
• When issued on a standalone (single-processor) switch, this command performs a cold reboot
of the switch.
• When issued on an enterprise-class platform (Brocade DCX, DCX-4S, or 48000) with two CPs
(active and standby), the following rules apply:
- When the Standby CP reboots, it goes down and there is no failover because there is no
traffic on that switch. When the Standby CP comes up again, it is temporarily no longer in
sync with the Active CP.
- When the Active CP reboots, it fails over to the Standby CP. The Standby CP becomes the
new Active CP and traffic is disrupted.
- When HA is in sync, and reboot -f is issued on the Active CP of a director, the Standby CP
takes over as the active CP without traffic disruption. If HA is not in sync, and reboot -f is
issued on the Active CP, the Standby CP takes over as the Active CP and traffic is
disrupted.
- When HA is disabled and reboot or reboot -f is issued on the Active CP, both the Active and
Standby CPs reboot with the original mastership retained. The original Active CP remains
the Active CP after the reboot, and the original Standby CP remains the Standby CP. After
the reboot, HA is enabled.
- When HA is disabled and reboot or reboot -f is issued on the Standby CP, the Standby CP
reboots without prompting. It boots up with the default switch only, even if the Active CP
has multiple logical switches configured. After the Standby CP boots up, HA is still
disabled.
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.
Operands -f Causes the CP to fail over to the Standby CP without affecting any of the Fibre
Channel Ports. Note that the recommended way to force a failover without
affecting any Fibre Channel ports is to issue the haFailover command.
Examples To reboot a standalone switch with a single CP:
switch:admin>
reboot
Warning: This command would cause the switch to reboot
and result in traffic disruption.
Are you sure you want to reboot the switch [y/n]?
