Update the Firmware on a Specific Device
To update the firmware on a specific device, run a firmware update tool on the device:
NOTE: The firmware update process is device-specific. This means that while the user interface to the update process
remains consistent, the specifics of the process for a given device may vary considerably. This procedure is an example
only, using a SCSI disk. CAUTION: Be sure that you put the firmware file on the UUT (for example, with FTP),
before starting the update process.
1. Select Device(s).
2. If desired, Select/Deselect Test Options.
3. Type FirmwareUpdate or "FWU". CAUTION: Make sure that you select the correct firmware file for the
device! Updating a device with incorrect firmware can make the device permanently unusable and data could be
lost.
CAUTION: If absolutely necessary, you can interrupt or abort the firmware update process; however, it is not
advisable.
