• Location from which the server boots
• Order in which boot devices are invoked
For example, you can choose to 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 must include this policy 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, the server uses the default settings in
the BIOS to determine the boot order.
Changes to a boot policy may be propagated to all servers created with an updating service profile template
that includes that boot policy. Reassociation of the service profile with the server to rewrite the boot order
information in the BIOS is auto-triggered.

Chassis Discovery Policy
The chassis discovery policy determines how the system reacts when you add a new chassis. Cisco UCS
Manager uses the settings in the chassis discovery policy to determine the minimum threshold for the number
of links between the chassis and the fabric interconnect and whether to group links from the IOM to the fabric
interconnect in a fabric port channel.
Chassis Links
If you have a Cisco UCS domain that has some chassis wired with 1 link, some with 2 links, some with 4
links, and some with 8 links we recommend that you configure the chassis discovery policy for the minimum
number links in the domain so that Cisco UCS Manager can discover all chassis.
For Cisco UCS implementations that mix IOMs with different numbers of links, we recommend using
the platform max value. Using platform max insures that Cisco UCS Manager uses the maximum number
of IOM uplinks available.
Tip
After the initial discovery, you must reacknowledge the chassis that are wired for a greater number of links
and Cisco UCS Manager configures the chassis to use all available links.
Cisco UCS Manager cannot discover any chassis that is wired for fewer links than are configured in the chassis
discovery policy. For example, if the chassis discovery policy is configured for 4 links, Cisco UCS Manager
cannot discover any chassis that is wired for 1 link or 2 links. Reacknowledgement of the chassis does not
resolve this issue.
The following table provides an overview of how the chassis discovery policy works in a multi-chassis Cisco
UCS domain:
