Cloning servers allows users to apply patches and install or modify installed software on a managed server before propagating those changes to other servers.
After performing necessary maintenance tasks on one managed server, a cloning image can be collected from that server and deployed to other managed servers. This minimizes the time required for the software maintenance of multiple managed servers while reducing the risk of mistakes during operation.
Using the network parameter auto-configuration function also enables automatic configuration of public LAN settings for each cloned server. This is done by re-configuring the network interfaces used for the public LAN following deployment of a cloning image.
For details on the cloning function, refer to "Chapter 8 Cloning [Windows/Linux]" of the "ServerView Resource Coordinator VE Setup Guide".
Note
Software maintenance tasks performed using the cloning function only apply to servers that share the same hardware and software configuration.
Deployment of a cloning image will reset the VLAN settings used for the public LAN of each target server. Those settings need to be restored either manually or automatically using the network parameter auto-configuration function.
The following data will also be reset on the servers to which a cloning image is deployed. If necessary, this data should be manually backed up (copied) before deployment, and restored once complete.
