Centera Clusters - Getting Started

The Centera cluster can be configured as a disk library. The library can be configured on a MediaAgent with the Windows operating system. Centera SDK 3.2 P5 (includes support for application registration) is used by the MediaAgent software.

Add Centera Cluster Information

Before configuring the Centera Cluster as a disk library, the Centera Cluster information must be added. Cluster information includes the IP address or DNS name of the Centera cluster and the port ID through which the library must be accessed.

Also, appropriate Centera access requirements (for example, configuration of Centera Pea file) must be fulfilled before using the MediaAgent software to back up data to Centera.

Once the Centera cluster information is added and successfully detected, the MediaAgents in the CommCell can use this information to add a Centera disk library.

The following procedure describes the steps involved in adding a Centera Cluster.

  1. If you wish to use a PEA file, use the following steps to setup the environment variable for the Centera PEA file location.
    1. From your computer Desktop, right-click My Computer and click Properties.
    2. From the Advanced tab, click Environment Variables. In the Environment Variables dialog box, under System Variables, select New.
    3. In the Variable name field, enter CENTERA_PEA_LOCATION.
    4. In the Variable value field, add the full path to the PEA file including the file itself. For example, C:\PEA\Centera.pea. It is recommended that there are no spaces in either the folder location or the file name.
    5. Click OK, and then OK again. Reboot the computer to commit the variable.
  2. On the ribbon in the CommCell Console, click the Storage tab, and then click Library and Drive.

  3. Under Available MediaAgents, select the MediaAgents that are attached to the library and on which the library needs to be configured and then click Add >>.

    Click OK.

    • To configure any shared library, make sure that you select all of the MediaAgents that share the library.
    • If a device has already been configured for the MediaAgent, the device appears in the Library and Drive Configuration dialog box.
    • For cluster, select the cluster server as the MediaAgent.

  4. If a library is not configured, a message appears that asks you to configure the library. Click OK.

    If a library is already configured, this message does not appear. Subsequently, the detected devices are displayed with the detection status detect success in the Library and Drive Configuration dialog box.

  5. From the Library and Drive Configuration window, click the Start menu, point to Centera, and then select Cluster.

  6. From the Centera Cluster List dialog box, click on New Cluster.

  7. From the Centera Cluster dialog box, click on Add.

  8. From the Add Access Node dialog box, enter either the DNS name or IP address of the Centera cluster. Add a port number in the Centera cluster which can be used by the system to access it and then click OK.

  9. A message appears that asks you to select a MediaAgent to detect the cluster information.

    Click OK.

  10. Detect the Centera cluster using the following steps:
    1. In the Access Nodes box, select the DNS name or IP address you just added from the Access Node list.
    2. Select the MediaAgent from which you wish to detect the Center cluster from the Detect Information From MediaAgent list
    3. Click on Detect.

  11. The ClusterID, Capacity and Version information of the Centera cluster are displayed.

    If you encounter an error, verify and ensure that you have provided accurate information in the Add Access Node dialog box.

    Click OK.

  12. The Centera cluster is displayed. Click Close.

Configure a Centera Cluster as a Disk Library

The following procedure describes the steps involved in configuring a Centera cluster as a disk library.

  1. From the Library and Drive Configuration window, click the Start menu, point to Centera, and then click Add Centera Library.

  2. In the Add Disk Library dialog box, select the name of the MediaAgent that will control the library and click OK.

  3. Select the Centera cluster you wish to configure from the Centera Cluster list, and then click OK.

  4. The Centera cluster is added as the mount path to the Centera disk library.

    The disk library appears in the Library and Drive Configuration window with the configured status.
