reboot

reboot
Reboots the control processor (CP) in a switch or a director.
Synopsis reboot [-f]
Description When this command is issued on 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 online.
This command prompts for confirmation with a warning message. Consider the following before
issuing a reboot:
•
•
•
•
•
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.
Operands This command has the following operand:
-f
Examples To reboot a Control Processor when HA is disabled:
See Also fastboot, hafailover
760
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 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.
Specify this operand when you want to fail over to the Standby CP and not
affect 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. This operand is optional.
switch:admin> reboot
This command is being run on a control processor (CP) based system. Because HA
is disabled, it will cause both active CP and the standby CP to reboot. After
reboot, the HA will be enabled.
