Because each Sensor in a HA pair must be rebooted after the software update, it is important to update the software in the correct order.
Steps:
Push the software to each of the Sensors that are in the HA pair. You can follow one of these methods:
Load the image file on the primary Sensor.
Load the image file on the secondary Sensor.
Reboot the primary Sensor. After reboot, you need to verify the status of Sensor through CLI and confirm if it displays SIGFILE or NO_SIGFILE. If the Sensor displays NO_SIGFILE, manually deploy sigfile to the Sensor using Manager.
Now, reboot the secondary Sensor. After reboot, you need to verify the status of Sensor through CLI and confirm if it displays SIGFILE or NO_SIGFILE. If the Sensor displays NO_SIGFILE, manually deploy sigfile to the Sensor using Manager.
Use the Performance Charts to verify the performance of the Sensors. This is to make sure the upgrade was successful. For information on how to check Sensor performance from Performance Charts, see Trellix Intrusion Prevention System Product Guide.
