Fabric OS Command Reference 675

53-1001186-01

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 the following message:

Are you sure you want to reboot the active CP [y/n]?

Consider the following before issuing a reboot:

• 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.

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 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.

Examples To reboot a Control Processor:

switch:admin> reboot

Warning: This command is being run on a control processor (CP) based system

and will cause the active CP to reboot.

Are you sure you want to reboot the active CP [y/n]?y
