When accessing UEFI BIOS configurations on the service processor (SP), ubiosconfig can be used over a local Host-to-ILOM interconnect or a remote Ethernet network connection as follows:

• When using local access, ubiosconfig uses the fastest local interface available. If a Host-to-ILOM connection is available this fast connection is used, otherwise the slower KCS interface is used. See Host-to-ILOM Interconnect.

  Note:

  For systems with an Oracle ILOM version earlier than 3.2.4, you must manually include credentials using the -H and -U options (described below) for any commands that access a service processor. If credentials are not provided the commands will default to the slower local KCS interface to access the local service processor.

• When using remote Ethernet network access, ubiosconfig must present login credentials using a command line argument (SP hostname and user account with root access as described in Command Options for Accessing Oracle ILOM Over a Remote Network Connection). In addition, command execution over a remote network connection is encrypted using the TLS protocol. This means that a client-side trusted SSL certificate for the Oracle ILOM SP being accessed must be present on the host to validate the connection. This certificate checking feature is the default for a remote network connection when using the fwupdate, ilomconfig and ubiosconfig commands.
