Booting from the Flexible Flash

You can specify a bootable virtual drive on the Cisco Flexible Flash card that will override the default boot priority the next time the server is restarted, regardless of the default boot order defined for the server. The specified boot device is used only once. After the server has rebooted, this setting is ignored.

Note Before you reboot the server, ensure that the virtual drive you select is enabled on the Cisco Flexible Flash card.

Before You Begin

•You must log in with admin privileges to perform this task.

•Cisco Flexible Flash must be supported by your platform.

Procedure

	Command or Action	Purpose
Step 1	Server# scope bios	Enters the BIOS command mode.
Step 2	Server /bios # set boot-override	The virtual drive from which the server attempts to boot the
	{None SCU HV HUU}	next time it is restarted. This can be one of the following:
		• None—The server uses the default boot order
		• SCU—The server boots from the Cisco UCS Server
		Configuration Utility
		• HV—The server boots from the hypervisor virtual drive
		• HUU—The server boots from the Cisco Host Upgrade
		Utility
Step 3	Server /bios # commit	Commits the transaction to the system configuration.

This example specifies that the server boots from the Cisco UCS Server Configuration Utility the next time it is restarted:

Server# scope bios

Server /bios # set boot-override SCU

Committing the boot override BIOS will try boot to the specified boot device first. Failure to detect the boot device BIOS will boot from the list configured in the BIOS boot order.
