Restoring a Snapshot backup

If data loss or data corruption occurs, you can restore Unified Manager to the previous stable state with minimum loss of data. You can restore the Unified Manager Snapshot database to a local or remote Red Hat Enterprise Linux or CentOS system by using the Unified Manager maintenance console.

Before you begin

You must have the root user credentials for the Linux host on which Unified Manager is installed.
You must have a user ID and password authorized to log in to the maintenance console of the Unified Manager server.

About this task

The restore feature is platform-specific and version-specific. You can restore a Unified Manager backup only on the same version of Unified Manager.

Procedure

Using Secure Shell, connect to the IP address or fully qualified domain name of the Unified Manager system.
Log in to the system with the maintenance user (umadmin) name and password.
Enter the command maintenance_console and press Enter.
In the maintenance console Main Menu, enter the number for the Backup Restore option.
Enter the number for Backup and Restore using NetApp Snapshot.
If you are performing a restore onto a new server, after installing Unified Manager do not launch the UI or configure any clusters, users, or authentication settings when the installation is complete. Enter the number for Configure NetApp Snapshot Backup and configure the Snapshot backup settings as they were configured on the original system.
Enter the number for Restore using NetApp Snapshot.
Select the Snapshot backup file that you want to restore and press Enter.
After the restore process is complete, log in to the Unified Manager user interface.

After you finish

After you restore the backup, if the OnCommand Workflow Automation server does not work, perform the following steps:

On the Workflow Automation server, change the IP address of the Unified Manager server to point to the latest machine.
On the Unified Manager server, reset the database password if the acquisition fails in step 1.
