USB storage mount
The USB storage supports the FAT file system. The USB storage does not automatically mount. To use USB storage, you must
first mount the device.
1. Create a mount directory for the USB.
ONIE:/ # mkdir /mnt/usb
2. View the fixed disks using the fdisk command.
ONIE:/mnt # fdisk -l
For internal storage:
Disk /dev/sda: 15.8 GB, 15829303296 bytes
255 heads, 63 sectors/track, 1924 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 1 1925 15458303+ ee EFI GPT
For USB storage:
Disk /dev/sdb: 30.9 GB, 30942946304 bytes
64 heads, 32 sectors/track, 29509 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes
Device Boot Start End Blocks Id System
3. Mount the device /dev/sdb to the /mnt/usb directory.
ONIE:/ # mount -t vfat /dev/sdb /mnt/usb
NOTE:
The following message displays if the /mnt/usb directory is missing: mount: mounting /dev/sdb
on /mnt/usb failed: No such file or directory.
NOTE: The following message displays if the USB device is not seen: mount: mounting /dev/sdb on /mnt/usb
failed: No such device or address.
4. OPTIONAL: Add a device to the file systems table, fstab, and mount the file systems.
ONIE:/ # vi /etc/fstab
# FSTAB entry for the ONIE-BOOT partition mounted on /boot
LABEL=ONIE-BOOT /mnt/onie-boot ext4 defaults,rw,errors=remount-ro 0 1
/dev/sdb /mnt/usb vfat defaults 0 1
ONIE:/ # mount -a
Before you install an OS
After powering on the S3048-ON switch, it goes through a power-on self-test (POST).
POST runs every time the switch is initialized and checks the hardware components to determine if the switch is fully
operational before booting. After POST, the switch uses the Grub bootloader.
To select which entry is highlighted, use the up and down arrow keys. Press Enter to select an OS or enter e to edit the
commands before booting. Enter c for a command line. The highlighted entry executes automatically in the operating system.
Example of the Grub Bootloader
GNU GRUB version 2.02~beta2+e4a1fe391
