Introduction

This document describes the procedure to revert and redeploy an Email Security Appliance (ESA) or Security Management Appliance (SMA).

Solution

Hardware Appliances (ESA / SMA)

Steps to clean and revert a physical appliance.

1. SSH to the appliance and run version and make note of the active version running on the appliance.

2. Run Revert, select a version of code that is older than From #1 and type Y.

sma.example.com> revert

This command will revert the appliance to a previous version of AsyncOS.

WARNING: Reverting the appliance is extremely destructive.

The following data will be destroyed in the process:

- all configuration settings (including listeners)

- all log files

- all databases (including messages in Virus Outbreak and Policy quarantines)

- all reporting data (including saved scheduled reports)

- all message tracking data

- all Cisco IronPort Spam Quarantine messages

and end-user safelist/blocklist data

Only the network settings (except the 'allow_arp_multicast' configuration variable)

will be retained. If you need to establish connectivity to a Microsoft Network Load Balancer,

you must configure the 'allow_arp_multicast' configuration variable after the revert process

is complete.

Before running this command, be sure you have:

- saved the configuration file of this appliance (with passwords unmasked)

- exported the Cisco IronPort Spam Quarantine safelist/blocklist database

to another machine (if applicable)

- waited for the mail queue to empty

Reverting the device causes an immediate reboot to take place.

After rebooting, the appliance reinitializes itself and reboots

again to the desired version.

Available versions

=================

1. 16.0.1-010

2. 16.0.2-088

3. 16.0.3-016

Please select an AsyncOS version [2]: 1

Do you want to continue? [N]> y

Are you sure you want to continue? [N]> y

Warning: This procedure will wipe the configuration, data and history of upgrades on the appliance

4. Allow the machine to complete revert and it is expected to take approximately 30 minutes to complete.

3. Once revert is complete and appliance is up, access the command line again and execute Reload via Diagnostic.

esa.example.com> diagnostic

Choose the operation you want to perform:

- RAID - Disk Verify Utility.

- NETWORK - Network Utilities.

- REPORTING - Reporting Utilities.

- TRACKING - Tracking Utilities.

- RELOAD - Reset configuration to the initial manufacturer values.

- RELOAD_STATUS - Display status of last reload run

- SERVICES - Service Utilities.

[]> reload

This command will remove all user settings and reset the entire device.

If this is a Virtual Appliance, all feature keys will be removed, and the license must be reapplied. This resets network configuration to factory defaults. You might lose connection to the device if you are connected remotely.

Are you sure you want to continue? [N]> y

Are you *really* sure you want to continue? [N]> y

Do you want to wipe also? Warning: This action is recommended if the device is being sanitized before sending it for RMA.

Sometimes, it may take several minutes to complete the process because it follows the NIST Purge standard. Do you want to continue? [N]> y

Reverting to "virtualimage" preconfigure install mode.

Virtual Appliances (ESA / SMA)

For information on hardware requirements, supported hypervisor platform please refer https://www.cisco.com/c/dam/en/us/td/docs/security/content_security/virtual_appliances/Cisco_Content_Security_Virtual_Appliance_Install_Guide.pdf.

VMware ESXi

1. Download the virtual appliance image and MD5 hash from Cisco.

2. Unzip the .zip file for the virtual appliance in its own directory; for example, C:\vESA\C100V.

3. Open the VMware vSphere Client on your local machine.

4. Select the ESXi host or cluster to which you want to deploy the virtual appliance.

5. Choose File > Deploy OVF template.

6. Enter the path to the OVF file in the directory you created and click Next. Complete the wizard.

7. If DHCP is disabled, set up the appliance on your network. Install the license file.

8. Log in to the web UI of your appliance and configure the appliance software.

Microsoft Hyper-V

1. Download the virtual appliance image and MD5 hash from Cisco.

2. Open Hyper-V Manager, use the "New Virtual Machine Wizard" to create a new virtual machine.

3. Assign the recommended hardware resources. (refer to virtual installation guide)

4. Attach the downloaded virtual appliance image as the virtual hard disk. Complete the wizard and start the virtual machine.

5. If DHCP is disabled, set up the appliance on your network. Install the license file.
