Upgrading the appliance using the CLI

Use the commands in the following sections to upgrade the Central Management System appliance.

Task list for upgrades

Perform the following steps (detailed in the sections that follow) to upgrade the appliance.

Important

Be sure to download the software image files from the configured DTI source server before beginning any installations.

Download and install the appliance software image

To download and install the software image:

Go to CLI configuration mode:

hostname > enable
hostname # configure terminal

Check for downloads:

hostname (config) # fenet image check
hostname (config) # show fenet image status

Download the software image:
```
hostname (config) # fenet image fetch
```

View the download progress:

hostname (config) # show fenet image status

Note

If you have already downloaded the latest software, you may see an error: "Latest image already downloaded and ready to install (error)." To check which images are downloaded, use the following command:

hostname (config) # show fenet image list

Install the downloaded software image:
```
hostname (config) # image install image-lms_7.9.0.img
hostname (config) # image boot next
```
Note
If an upgrade process is interrupted or fails, the appliance software automatically falls back to the currently installed image.
Save your changes:
```
hostname (config) # write memory
```

Restart the appliance and accept the EULA

To restart the appliance and accept the EULA:

Go to CLI configuration mode:

hostname > enable
hostname # configure terminal

Restart the appliance:
```
hostname (config) # reload
```
After restarting the appliance, the system could display the Trellix End User License Agreement (EULA). Read the EULA. Click Yes if you agree to its terms, and then click Submit. If you do not accept the EULA, the appliance will not function.
After accepting the EULA, the login page is displayed. Wait a few minutes before logging in because database records are undergoing an update in preparation for the upgrade.
Note
You must access the appliance through the serial port if you want to monitor appliance boot activities. You can enter CLI commands through direct keyboard and monitor connection only before the boot loader begins loading the kernel, for example, to post output, and after the boot is completed.

Verify the upgrade

To verify the upgrade:

Go to CLI configuration mode:

hostname > enable
hostname # configure terminal

Display the version information for the current system image:
```
hostname (config) # show version
```
