Change UEFI boot order

If not created already, create an instance of Rest or Redfish Object using the RestObject or RedfishObject class respectively. The class constructor takes iLO hostname/ ip address, iLO login username and password as arguments. The class also initializes a login session, gets systems resources and message registries.

Rest Object creation:

REST_OBJ = RestObject(iLO_host, login_account, login_password)

Redfish Object creation:

REDFISH_OBJ = RedfishObject(iLO_host, login_account, login_password)

Example 7: Change UEFI boot order

The method ex7_change_boot_order takes an instance of rest object (or redfish object if using Redfish API) and BIOS password (default None) as arguments.

def ex7_change_boot_order(restobj, bios_password=None):

Find and get the server boot settings URI(s) from the system resource collection.

instances = restobj.search_for_type("ServerBootSettings.1")

Send a HTTP GET request to the server boot settings URI(s) retrieved.

for instance in instances:
       response = restobj.rest_get(instance["href"])

Get the boot order from the response body.

bootorder = response.dict["PersistentBootConfigOrder"]

Set up PATCH request body.

body = dict()
body["PersistentBootConfigOrder"] = bootorder

PATCH request is sent next and response error is handled if any.

response = restobj.rest_patch(instance["href"], body, optionalpassword=bios_password)
restobj.error_handler(response)

A successful PATCH response will set the Boot order in BIOS, however the settings remain pending until next reboot.
