3 Software reboot

Software reboot

You can use boot commands to immediately initiate software boots from a software image stored in primary or secondary flash on a Brocade device or from a BootP or TFTP server. You can test new versions of code on a Brocade device or choose the preferred boot source from the console boot prompt without requiring a system reset.

NOTE

It is very important that you verify a successful TFTP transfer of the boot code before you reset the system. If the boot code is not transferred successfully but you try to reset the system, the system will not have the boot code with which to successfully boot.

By default, the Brocade device first attempts to boot from the image stored in its primary flash, then its secondary flash, and then from a TFTP server. You can modify this booting sequence at the global CONFIG level of the CLI using the boot system… command.

To initiate an immediate boot from the CLI, enter one of the boot system… commands.

NOTE

When using the boot system tftp command, the IP address of the device and the TFTP server should be in the same subnet.

Software boot configuration notes

If you are booting the device from a TFTP server through a fiber connection, use the following command: boot system tftp <ip-address> <filename> fiber-port.
