Upgrade Lighthouse via the CLI

Lighthouse includes a shell-based tool — sysflash — that allows a user with administrative privileges to upgrade the system for the instance from the local terminal.

Note:  Before you use sysflash, we recommend that you check available disk space when manually uploading .lh upgrade files. We also suggest you use /mnt/nvram as the path.

Upgrade via Local Terminal

To upgrade the system for the Lighthouse instance using the Lighthouse local terminal:

  1. Select Terminal.

  2. At the [hostname] login: prompt, enter an administrator username and press Enter.

  3. At the Password: prompt, enter the administrator’s password and press Enter.

  4. To use sysflash with a .lh_upg file available via an HTTP or HTTP server, at the local terminal bash shell prompt, enter a URL that it is URL encoded.

    >sysflash http[s]%3A%2F%2Fdomain.tld%2Fpath%2Fto%2Ffirmware-upgrade- image.lh_upg

  5. Press Enter.

Upgrade via Local File System

To upgrade Lighthouse with sysflash and a .lh_upg file available via the local file system:

  1. Select Terminal.

  2. At the [hostname] login: prompt, enter an administrator username and press Enter.

  3. At the Password: prompt, enter the administrator’s password and press Enter.

  4. At the local terminal bash shell prompt enter:

    >sysflash /path/to/system-upgrade-image.lh_upg

  5. Press Enter.

Note:  sysflash includes several flags that allow for variations in the standard system upgrade process. These flags should not be used unless directed to do so by Opengear Support.

List the flags by running either of the following at a local terminal bash shell prompt:

sysflash -h or

sysflash --help
