 The command will update firmware for NeXtScale FPC when given an FPC node and the http information needed to access the firmware. The http imformation required includes both the MN IP address as well as the directory containing the firmware. It is recommended that the firmware be downloaded and placed in the /install directory structure as the xCAT MN /install directory is configured with the correct permissions for http.
