• Location from which the server boots
• Order in which boot devices are invoked
Forexample, you canchoose to haveassociated servers boot froma local device, such asa localdisk or
CD-ROM(VMedia), or you can select a SAN boot or a LAN (PXE) boot.
Youmust include this policy in a service profile, and that service profile must be associated with a server for
itto take effect. If you do not include a boot policy in a service profile, the server uses the default settings in
theBIOS to determine the boot order.
Changesto a boot policy may be propagated to all servers created with an updating service profile template
thatincludes that boot policy. Reassociation of the service profile with the server to rewrite the boot order
informationin the BIOSis auto-triggered.
Important
Chassis Discovery Policy
Thechassis discovery policy determines how the systemreacts when you adda newchassis. Cisco UCS
Manageruses the settings in the chassis discovery policy to determine the minimum threshold for the number
oflinks between the chassis and the fabric interconnect and whether to group links from the IOM to the fabric
interconnectin a fabricport channel.
Chassis Links
Ifyou havea CiscoUCS 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
numberlinks in thedomain so that Cisco UCS Managercan discover all chassis.
ForCisco UCSimplementations that mixIOMs withdifferent numbers of links, werecommend using
theplatform max value. Using platform max insures that Cisco UCS Manager uses the maximum number
ofIOM uplinksavailable.
Tip
Afterthe initial discovery, you must reacknowledge the chassis that are wired for a greater number of links
andCisco UCSManager configures thechassis to useall availablelinks.
CiscoUCS Manager cannot discover any chassis that is wired for fewer links than are configured in the chassis
discoverypolicy. For example, if the chassis discovery policy is configured for 4 links, Cisco UCS Manager
cannotdiscover any chassis that iswired for 1link or2 links.Reacknowledgement of the chassis does not
resolvethis issue.
