Duplicate Serial Number error message Edge SWG VA

Products

• ProxySG Software - SGOS

Issue/Introduction

The Duplicate Serial Number error displays in the Management Console.

The virtual appliance serial number is a unique identifier that can be used in only one instance of a Edge SWG (ProxySG) Virtual Appliance.  You are receiving this error because Blue Coat detects more than one SWG VA sharing the same serial number.

Note:  Web Protection Suite (ISG Proxy)  Enterprise license serial number can be used on multiple instances without issue.

 

 

Resolution

 This issue automatically resolves itself within an hour of SWG VA runtime. If you issued the CLI command multiple times shortly before the Duplicate Serial Number error occurred, wait an hour for the error to clear. 

Cause 1

You issued the restore-defaults factory-defaults command in the command line interface (CLI) multiple times in a short period of time, which caused the SWG VA to identify itself incorrectly as a duplicate. 

The presence of a warning beside License Validation Status on the Health Monitoring tab (Maintenance > Health Monitoring) may also indicate that the SWG VA identifies itself as a duplicate.

If the restore-defaults factory-defaults command was not issued and there is no warning in Health Monitoring, proceed to Cause 2.

 

Cause 2

Multiple SWG VAs in the network are using identical appliance serial numbers, and the license has been suspended.

Resolution

Complete the following steps:

1. Identify which SWG VAs in your network are using identical appliance serial numbers. The serial number is displayed on the Management Console banner.
2. Decide which SWG VAs to retain.
3. (Optional) Back up the configuration of the duplicate SWG VA. You can later restore this configuration to another SWG VA (one that has a unique serial number).
4. Delete the duplicate SWG VA. To delete the duplicate SWG VA on the ESX host, select it, right-click and choose Delete from Disk.
   Note: You cannot edit the serial number on a SWG VA. To replace this instance of the SWG VA, you must purchase a new appliance serial number and recreate a SWG VA. Contact your Blue Coat Sales Representative to purchase a new appliance serial number. 
5. (Optional) If you do not want to wait an hour for the SWG VA to determine that there are no longer duplicate serial numbers in use, reboot the SWG VA.

Note:  Beginning with SGOS 7.2.5.1 (6.7.5.10), you now have the option to clear virtual appliance serial numbers when restoring factory defaults.
