Uninstalling the Update

To uninstall the update:

1. Read and understand 

 on page 15.

2. Log into the appliance’s shell using an account with Administrator privileges 

via the virtual console in the VMware vSphere Client. Note that you must type 

expert

 to display the shell prompt.

3. At the prompt, run the uninstallation as the root user, providing your 

password when prompted:

sudo install_update.pl /var/sf/updates/

update_name

Where 

update_name

 is the file name of the update you downloaded earlier.

The uninstallation process begins. When the uninstallation is complete, the 

appliance reboots.

If you encounter issues with the uninstallation, do not restart 

the uninstallation. Instead, contact Support.

4. After the uninstallation finishes, log into the managing Defense Center and 

select Devices > Device Management. Confirm that the device where you 

uninstalled the update has the correct software version: Version 5.2.0.5.

5. Verify that the appliances in your deployment are successfully communicating 

and that there are no issues reported by the health monitor.

Uninstalling the Update from a Defense Center

Use the following procedure to uninstall the Version 5.2.0.6 update from Defense 

Centers and virtual Defense Centers. Note that the uninstallation process reboots 

the Defense Center.
Uninstalling the Version 5.2.0.6 update results in a Defense Center running 

Version 5.2.0.5. For information on uninstalling a previous version, refer to the 

release notes for that version.

To uninstall the update:

1. Read and understand 

 on page 15.

2. Make sure that the appliances in your deployment are successfully 

communicating and that there are no issues reported by the health monitor.

3. View the task queue (System > Monitoring > Task Status) to make sure that 

there are no tasks in progress.
Tasks that are running when the uninstallation begins are stopped, become 

failed tasks, and cannot be resumed; you must manually delete them from 

the task queue after the uninstallation completes. The task queue 

automatically refreshes every 10 seconds. You must wait until any 

long-running tasks are complete before you begin the uninstallation.
