You can backup your cluster configuration data from the Backing up a Cluster Configuration panel.
This task assumes that you have already launched the SAN Volume Controller Console.
The backup function is designed to back up information about your cluster configuration, such as virtual disks (VDisks), local Metro Mirror information, local Global Mirror information, managed disk (MDisk) groups, and nodes. All other data that you have written to the VDisks is not backed up. Any application that uses the VDisks on the cluster as storage, must back up its application data using appropriate backup methods.
You must regularly back up your cluster configuration data and your application data to avoid data loss. If a cluster is lost after a severe failure occurs, both cluster configuration and application data is lost. You must reinstate the cluster to the exact state it was in prior to the failure and then recover the application data.
The backup function creates three files that provide information about the backup process and cluster configuration. When you use the SAN Volume Controller Console to perform the backup, these files are created in the \console\ClusterConfiguration.backup\cluster directory of the IBM® System Storage® Productivity Center or the master console. Where console is the directory where the SAN Volume Controller Console is installed and cluster is the name of the cluster for which you want to back up the cluster configuration data.
| File name | Description |
|---|---|
| svc.config.backup.xml | This file contains your cluster configuration data. |
If the svc.config.backup.xml file already exists in the directory, it is renamed to svc.config.backup.bak. After the file is renamed the new svc.config.backup.xml is written.
Complete the following steps to backup your cluster configuration data:
