This article shows you how to recover disconnected SQL cluster service when the firewall driver is updated in Worry-Free Business Security (WFBS).
Upgrading the Client Security Agent will update the firewall driver on the client side. The network connection will be temporarily disconnected during the update of firewall driver. This will lead to SQL cluster disconnection, and will require you to configure the setting manually in order to recover the SQL cluster service.
Do the following:
- Restart the cluster services.
- Bring all other cluster group resources online.
- Move the cluster group resources to the main active node.
The cluster operation will now be restored.
