4.7 USB Support
4.7.1 Accessing a USB Device for Read/Write
MLNX-OS can access USB devices attached to switch systems. USB devices are automatically
recognized and mounted upon insertion. To access a USB device for reading or writing a file, you
need to provide the path to the file on the mounted USB device in the following format:
scp://username:password@hostname/var/mnt/usb1/<file name>
Examples:
 T
o fetch an image from a USB device, run the command:
 To save log file ‘3’ to a USB device under the name
test_log_f using the logging files
command, run (in Enable or Config mode):
 To safely remove the USB and to flush the cache, after writing (log files, for example) to a
USB, use the
usb eject command (in Enable or Config mode).
For further information, please
refer to Mellanox MLNX-OS Command Reference Guide.

Step 1. Connect to the system from the host SSH.
Step 2. Add the -h parameter after the cli (as shown in the example below) to notify the system to halt
on failure and pass through the exit code.
