You can update your existing Unified Manager installation and configure your setup environment for high availability.

Before you begin

  • You must have created a backup and support bundle of your existing data.

  • You must have the OnCommand Administrator or Storage Administrator role.

  • You must have added a second node to your cluster and installed Veritas Cluster Server (VCS) on the second node.

    See the Veritas Cluster Server 6.2.1 Installation Guide.

  • The newly added node must be configured to access the same shared location as that of the existing node in the high-availability setup.

Steps

  1. Log in to the new node of the cluster.

  2. Install Unified Manager on the node.

    Installing Unified Manager on Red Hat Enterprise Linux or CentOS

  3. Configure the Unified Manager server using configuration scripts on the existing node with data.

  4. Initiate manual fail over to the second node.

  5. Run the perl ha_setup.pl --join -t vcs -f``mount_path command on the second node of the cluster so that the Unified Manager server data points to the shared LUN.

  6. If OnCommand Workflow Automation (WFA) is configured for Unified Manager, disable and then reconfigure the WFA connection.

  7. If SnapProtect is configured with Unified Manager, reconfigure SnapProtect with a new cluster IP address and the existing storage policies.

  8. Regenerate the custom reports and add these reports to Unified Manager with the new cluster IP address.
