Table 5.61 Flash Firmware with ROM File (Cont.) Description Flashes the firmware with the ROM file specified at the command line. The -NoSigChk option forces the application to flash the firmware even if the check word on the file does not match the required check word for the controller. This option flashes the firmware only if the existing firmware version on the controller is lower than the version on the ROM image. If you specify -NoVerChk, also, the application flashes the controller firmware without checking the version of the firmware image. The version check applies only to the firmware (APP.ROM) version. This command also supports the "Mode 0" flash functionality. For Mode 0 flash, the controller number is not valid. There are two possible methods: • Select which controller to flash after the controllers are detected. • Flash the firmware on all present controllers. XML output data is generated by this option. 5.13.2 Flash the Firmware in Mode 0 with the ROM File Use the command in Table 5.62 to flash the firmware in Mode 0 with the ROM file specified at the command line for the selected controller(s). This option is for DOS only. Table 5.62 Flash Firmware in Mode 0 with ROM File Convention Description MegaCli -AdpM0Flash -f filename Flashes the firmware in Mode 0 with the ROM file listed on the command line. This option supports the Mode 0 flash functionality. For Mode 0 flash, the controller number is not valid. The method to handle this is to flash the firmware on all present controllers which are compatible with the image. 5.14 SAS Topology The commands in this section are used to display SAS topology. Use the command in Table 5.63 to display the PHY connection information for physical PHY M on the selected controller(s). Each PHY can form one side of the physical link in a connection with a PHY on a different device. The physical link contains four wires that form two differential signal pairs. One differential pair transmits signals, and the other differential pair receives signals. Both differential pairs operate simultaneously and allow concurrent data transmission in both the receive and the transmit directions. PHYs are contained within ports. 5-36 MegaRAID Command Tool
