Using the USB Flash Drive

Using the USB Flash Drive
An Alcatel-Lucent certified USB flash drive can be connected the CMM and used to transfer images to
and from the flash memory on the switch. This can be used for upgrading switch code or backing up files.
Additionally, automatic code upgrades as well as the capability to boot from the USB flash drive for disas-
ter recovery purposes are also supported. For the automatic upgrades and disaster recovery the USB flash
drive must be configured with the proper directory structure, depending on the platform, as noted in the
following table. Once the flash drive is properly mounted a directory named /uflash is automatically
created. Files can then be copied to and from the /uflash directory.
The directories below must be created on the USB flash drive for feature support.

Transferring Files Using USB

The following is an example of how to mount and transfer files using the USB flash drive using the
and umount commands.
-> usb enable
-> cp /flash/working/boot.cfg /uflash/boot.cfg
-> umount /uflash
Once the USB flash drive is mounted most common file and directory commands can be performed on the
/uflash directory.

Automatically Upgrading Code Using USB

The switch can be configured to automatically mount and copy image files from the USB flash drive as
soon as it's connected. This can be used to automatically upgrade code. In order to prevent an accidental
upgrade, a file named aossignature must be stored on the USB flash drive as well as having a directory
with the same name as the product family as noted in the table above. The following is an example for an
OmniSwitch 6250 using the
Note: The aossignature file can be an empty text file.
1 Create a file named aossignature in the root of the USB flash drive.
2 Create a directory named 6250/working on the USB flash drive with all the proper image files.

-> usb enable

-> usb auto-copy enable
5 Connect the USB flash drive to the CMM. The presence of image files are checked and copied to the
related /uflash/6250/certified (or /uflash/6450/certified) directory of the CMM. The switch now reboots
from the working directory applying the code upgrade.
6 Once the switch reboots the auto-copy feature is automatically disabled to prevent another upgrade.
