fastBoot

fastBoot
Reboots the Control Processor (CP), bypassing the Power-On Self-Tests (POST).
Synopsis fastboot
Description Use this command to perform a "cold reboot" (power off/restart) of the control processor
bypassing POST when the system comes back up. Bypassing POST can reduce boot time
significantly. If POST was previously disabled using the diagDisablePost command, then fastBoot is
the same as reBoot.
The fastBoot operation is 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 varies according to platform type:

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.

Examples To reboot a standalone (single-processor) switch without executing POST on startup:
244
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 disabled and fastBoot 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 fastBoot 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.
switch:admin> fastboot
Warning: This command would cause the switch to reboot
and result in traffic disruption.
