Installing SnapCenter Plug-ins Package for Linux on cluster host

You should install SnapCenter Plug-ins Package for Linux on both the nodes of the cluster host.

About this task

Each of the nodes of the cluster host has two IPs. One of the IPs will be the public IP of the respective nodes and the second IP will be the cluster IP that is shared between both the nodes.

Steps

  1. Install SnapCenter Plug-ins Package for Linux on both the nodes of the cluster host.
    See Installing the SnapCenter Plug-ins Package for Linux interactively.
  2. Validate that the correct values for SNAPCENTER_SERVER_HOST and SPL_ENABLED_PLUGINS parameters are specified in the spl.properties file located at /var/opt/snapcenter/spl/etc/.
    • SNAPCENTER_SERVER_HOST=server_IPaddress
    • SPL_ENABLED_PLUGINS=SCO,SCU
  3. On the SnapCenter Server host, establish a session using the Open-SmConnection cmdlet, and then enter your credentials.
  4. In each of the nodes, set the preferred IPs of the node using the Set-PreferredHostIPsInStorageExportPolicy sccli command and the required parameters.

    The information regarding the parameters that can be used with the command and their descriptions can be obtained by running help command_name. Alternatively, you can also refer to the Command Reference Guide.

  5. In the SnapCenter Server host, add an entry for the cluster IP and corresponding DNS name in C:\Windows\System32\drivers\etc\hosts.
  6. Add the node to the SnapCenter Server using the Add-SmHost cmdlet by specifying the cluster IP for the host name.

    The information regarding the parameters that can be used with the cmdlet and their descriptions can be obtained by runningGet-Help command_name. Alternatively, you can also refer to the Cmdlet Reference Guide.

After you finish

Discover the Oracle database on node 1 (assuming the cluster IP is hosted on node 1) and create a backup of the database. If a fail over happens, you can use the backup created on node 1 to restore the database on node 2. You can also use the backup created on node 1 to create a clone on node 2.
Note: There will be stale volumes, directories, and lock file if the fail over happens while any other SnapCenter operations are running.
