Upgrading and Analysis Engine

If you try to upgrade an IPS sensor, you may receive an error that Analysis Engine is not running:
sensor# upgrade scp://user@10.1.1.1/upgrades/IPS-K9-7.0-1-E3.pkg
Password: ********
Warning: Executing this command will apply a major version upgrade to the application
partition. The system may be rebooted to complete the upgrade.
Continue with upgrade?: yes
Error: AnalysisEngine is not running. Please reset box and attempt upgrade again.
If you receive this error, you must get Analysis Engine running before trying to upgrade again. This error
is often caused by a defect in the currently running version. Try rebooting the sensor, and after reboot,
run the setup command and remove the interfaces from the virtual sensor vs0. When it is not monitoring
traffic, Analysis Engine usually stays up and running. You can upgrade at this time. After the upgrade,
add the interfaces back to the virtual sensor vs0 using the setup command.
Or you can use the system image file to reimage the sensor directly to the version you want. You can
reimage a sensor because the reimage process does not check to see if Analysis Engine is running.
Reimaging using the system image file restores all configuration defaults.
