The Cisco UCS Manager enables you to create a boot policy for blade servers and rack servers.
The Cisco UCS Manager boot policy overrides the boot order in the BIOS setup menu and determines the following:
Selection of the boot device
Location from which the server boots
Order in which boot devices are invoked
For example, you can have associated servers boot from a local device, such as a local disk or CD-ROM (VMedia), or you can select a SAN boot or a LAN (PXE) boot.
You can either create a named boot policy to associate with one or more service profiles, or create a boot policy for a specific service profile. A boot policy must be included in a service profile, and that service profile must be associated with a server for it to take effect. If you do not include a boot policy in a service profile, Cisco UCS Manager applies the default boot policy.
Changes to a boot policy might be propagated to all servers created with an updating service profile template that includes that boot policy. Re-association of the service profile with the server to rewrite the boot order information in the BIOS is automatically triggered.
You can also specify the following for the boot policy:
