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

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

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 OS	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 or DAG	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.
   Run As name	Either select the Run As name that you created. or create new Run As credentials. The Run As credential must have administrative rights on the remote host. For details, see the information about creating Run As credentials. You can view details about the Run As credentials by positioning the cursor over the Run As credential name that you specified. Note: The Run As credentials authentication mode is determined by the host type that you specify in the Add Host wizard.
   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 by using a custom port, you must specify the same custom port. Otherwise, the operation fails.
   Add all hosts in the cluster or DAG	Select this checkbox to add all of the cluster nodes in an Oracle RAC.
   Check Fingerprint	Click Check Fingerprint to retrieve the fingerprint value. Verify the fingerprint, and then click Confirm Fingerprint. In a cluster setup, you should verify the fingerprint of each of the nodes in the cluster. Note: Fingerprint verification is mandatory even if the same host was added earlier to SnapCenter and the fingerprint was confirmed.
   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.

5. On the Installed plug-ins page, review the plug-in package that is installed on the host.
   For new deployments, no plug-in package is listed.
6. On the Plug-ins to install page, select the plug-in package, and then specify the plug-in ports and installation path.
   The default path is /opt/NetApp/snapcenter. You can optionally customize the path.
7. Click Next.
   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 either the web.config file located at C:\Program Files\NetApp\SnapCenter WebApp or the PowerShell config files located at C:\Windows\System32\WindowsPowerShell\v1.0\Modules\SnapCenter\ 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 the web.config, file you must update the file on both of the nodes.
8. After fixing any validation errors, click Validate.
9. Review the summary, and then click Finish.
10. Monitor the installation progress.
    You should refresh the Hosts page after a few minutes to view the newly added host.
    The installation-specific log files are located at /custom_location/snapcenter/logs.

    Note: If a firewall is enabled on the Linux host, the host status is displayed as down and the overall status is displayed as stopped on the Managed Hosts page. However, the SnapCenter Plug-ins Package for Linux is installed successfully.
