Adding hosts and installing the SnapCenter Plug-ins Package for Linux

You must use the SnapCenter Add Host page to add hosts, and then install the SnapCenter Plug-ins Package for Linux. The plug-ins are automatically installed on the remote hosts.

Before you begin

About this task

You can add a host and install plug-in packages either for an individual host or for a cluster. If you are installing the plug-in on a cluster (Oracle RAC), the plug-in is installed on all of the nodes of the cluster. For Oracle RAC One Node, you should install the plug-in on both active and passive nodes.

The administration documentation contains information about managing hosts.

Performing administrative tasks

Steps

  1. In the left navigation pane, click Hosts.
  2. Verify that the Managed Hosts tab is selected at the top.
  3. Click Add.
  4. On the Hosts page, perform the following actions:
    For this field… Do this…
    Host Type Select Linux as the host type.

    The SnapCenter Server adds the host, and then installs the Plug-in for Oracle Database and the Plug-in for UNIX if the plug-ins are not already installed on the host.

    Host name Enter the fully qualified domain name (FQDN) or the IP address of the host.

    SnapCenter depends on the proper configuration of the DNS. Therefore, the best practice is to enter the FQDN.

    You can enter the IP addresses or FQDN of one of the following:

    • Stand-alone host
    • Any node in the Oracle Real Application Clusters (RAC) environment

      Node VIP or scan IP is not supported

    If you are adding a host by using SnapCenter and the host is part of a subdomain, you must provide the FQDN.

    Credentials Either select the credential name that you created. or create new credentials.

    The credential must have administrative rights on the remote host. For details, see the information about creating credentials.

    You can view details about the credentials by positioning the cursor over the credential name that you specified.

    Note: The credentials authentication mode is determined by the host type that you specify in the Add Host wizard.
  5. In the Select Plug-ins to Install section, select the plug-ins to install.
  6. (Optional) Click More Options.
    For this field… Do this…
    Port Either retain the default port number or specify the port number.
    The default port number is 8145. If the SnapCenter Server was installed on a custom port, that port number will be displayed as the default port.
    Note: If you manually installed the plug-ins and specified a custom port, you must specify the same port. Otherwise, the operation fails.
    Installation Path The default path is /opt/NetApp/snapcenter. You can optionally customize the path.
    Add all hosts in the Oracle RAC Select this checkbox to add all of the cluster nodes in an Oracle RAC.
    Skip preinstall checks Select this checkbox if you already installed the plug-ins manually and you do not want to validate whether the host meets the requirements for installing the plug-in.
  7. Click Submit.
    If you have not selected the Skip prechecks checkbox, the host is validated to verify whether the host meets the requirements for installing the plug-in. If the minimum requirements are not met, appropriate error or warning messages are displayed.
    If the error is related to disk space or RAM, you can update the web.config file located at C:\Program Files\NetApp\SnapCenter WebApp to modify the default values. If the error is related to other parameters, you must fix the issue.
    Note: In an NLB setup, if you are updating web.config file, you must update the file on both nodes.
  8. Verify the fingerprint, and then click Confirm and Submit.
    In a cluster setup, you should verify the fingerprint of each of the nodes in the cluster.
    Note: SnapCenterdoes not support ECDSA algorithm.
    Note: Fingerprint verification is mandatory even if the same host was added earlier to SnapCenter and the fingerprint was confirmed.
  9. Monitor the installation progress.

    The installation-specific log files are located at /custom_location/snapcenter/logs.

Result

The configuration checker operation is triggered automatically and provides alerts for recommendations, corrective actions, and notifications to resolve the issues.

After you finish

After installing the plug-in, all of the databases on that host are automatically discovered and displayed in the Resources page. If nothing is displayed, click Refresh Resources.
