admin@sonic:~$ sudo mkdir /mnt/usb Create the USB mount location /mnt/usb.
admin@sonic:~$ sudo mount <USB device drive location> /mnt/usb       Mount the USB drive to the USB mount directory /mnt/usb.

Sample Output


In the below example, the USB is located in /dev/sdb. (Output Trimmed for brevity) 
admin@sonic:~$ sudo blkid
/dev/sda1: SEC_TYPE="msdos" LABEL_FATBOOT="EFI System" LABEL="EFI System" UUID="XXXXXXXXXXXXXXXXXXXXXX" TYPE="vfat" PARTLABEL="EFI System" PARTUUID="XXXXXXXXXXXXXXXXXXXXXX"
/dev/sda2: LABEL="ONIE-BOOT" UUID="XXXXXXXXXXXXXXXXXXXXXX" TYPE="ext4" PARTLABEL="ONIE-BOOT" PARTUUID="XXXXXXXXXXXXXXXXXXXXXX"
/dev/sda3: LABEL="SONiC-OS" UUID="XXXXXXXXXXXXXXXXXXXXXX" TYPE="ext4" PARTLABEL="SONiC-OS" PARTUUID="XXXXXXXXXXXXXXXXXXXXXX"
/dev/loop0: TYPE="XXXXXXXXXXXXXXXXXXXXXX"
/dev/loop1: UUID="XXXXXXXXXXXXXXXXXXXXXX" TYPE="ext4"
/dev/loop2: UUID="XXXXXXXXXXXXXXXXXXXXXX" TYPE="ext4"
/dev/sdb: LABEL="USB" UUID="XXXXXXXXXXXXXXXXXXXXXX" TYPE="vfat"

Create /mnt/usb directory and mount the USB in the directory.  
admin@sonic:~$ sudo mkdir /mnt/usb
admin@sonic:~$ sudo mount /dev/sdb /mnt/usb

admin@sonic:~$ sudo umount /mnt/usb
 

Copy File to and from a USB Drive Inserted in the Switch

Use cp command to copy a file from/to the mounted directory.

For example, in the below output, we are copying the show tech file (sonic_dump_sonic_20230520_013638) in /var/dump to /mnt/usb directory.
  
admin@sonic:~$ sudo cp /var/dump/sonic_dump_N3248TE-Sonic-Leaf42_20230520_013638.tar /mnt/usb/
