When updating system firmware including the service processor (SP), fwupdate can be used over a local Host-to-ILOM interconnect or a remote Ethernet network connection. When using local update, fwupdate 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.
When issuing a fwupdate command that accesses the service processor, login credentials are not required when using the local Host-to-ILOM interconnect, but they are required for a remote Ethernet network connection.
The credential options listed in the following table are supported for fwupdate when accessing a service processor over a network connection.
When using these options to access an SP connection, you must use both options together.
