This article describes how to reset the CloudBridge 400, 800, 2000, 3000, 4000 or 5000 appliance to factory default state by using XenServer (Dom0).
Note: This article applies to Citrix SD-WAN WANOP.

Requirements

• IP connectivity to the XenServer IP address.

• Serial console or LOM connection to the Cloud Bridge appliance to look at the output of the rebuild process.
  When the command to reset CloudBridge is initiated, it sets the appliance back to factory default IP address. This IP address cannot be reached, if routes are not built in your network for that range. Hence it is recommended to have serial console or LOM connection to the Cloud Bridge appliance.

Instructions

To reset the CloudBridge 400, 800, 2000, 3000, 4000 and 5000 appliances to factory default state by using XenServer, complete the following procedure:

1. Connect a serial cable to the serial port for monitoring the rebuild process.

2. Open a Secure Shell (SSH) session to the XenServer IP address and log on with the default credentials (root / nsroot).

3. Run the following commands to stop the IPMI timer before starting the factory reset process:
   service ftwd stop
   ipmitool mc watchdog off

   

   Note: You might see a different output for the ipmitool command when using CloudBridge 4000 or 5000 appliance. This can be safely ignored. However, if the output is different for CloudBridge 2000 or 3000 appliance, then troubleshoot the issue further.

4. Run the fdisk command on the sda partition:
   fdisk /dev/sda

   

5. Mark the first partition active, second partition not active, and change the partition type to 0xc:
   a<ENTER> 1 <ENTER>
   a <ENTER> 2 <ENTER>
   t <ENTER> 1 <ENTER> c <ENTER>

   

6. Verify the changes:
   p <ENTER>

   

7. Write the changes:
   w <ENTER>

   

8. Press Ctrl+C on the keyboard to exit fdisk.

9. Restart the system from Dom0:
   sync;sync;reboot

   

The rebuild process takes 20 to 30 minutes to complete. The system restarts into the XenServer installation process and completes multiple restarts. If the serial console is being monitored and if the system does not respond during the initial stage, then power cycle the appliance. Else, do not power off during the factory reset.

After the process is complete you will have CloudBridge appliance with factory default settings. The Management Service virtual machine should now be accessible by using the default IP 192.168.100.1 for initial configuration.

If your appliance is a CB4000 or CB5000, please refer to article CTX200902 on how to re-provision it to 7.2.2, and from here we can upgrade to 7.4.6, 9.0.1 and 9.x
