Adding hosts and installing Plug-in for Exchange

You can use the SnapCenter Add Host wizard to add Windows hosts. The Plug-in for Exchange is automatically installed on the specified host. This is the recommended method for installing plug-ins. You can add a host and install a plug-in either for an individual host or a cluster.

Before you begin

You must be a user that is assigned to a role that has the plug-in install and uninstall permissions, such as the SnapCenter Admin.

About this task

You can add a host and install plug-in packages either for an individual host or a cluster. If you are installing plug-ins on a cluster (Exchange DAG), they are installed on all of the nodes of the cluster.

Plug-in for Exchange depends on SnapCenter Plug-ins Package for Windows and the versions must be the same. During the Plug-in for Exchange installation, SnapCenter Plug-ins Package for Windows is selected by default and is installed along with the VSS Hardware Provider.

If SnapManager for Microsoft Exchange Server and SnapDrive for Windows are already installed, and you want to install Plug-in for Exchange on the same Exchange Server, you must unregister the VSS Hardware Provider used by SnapDrive for Windows because it is incompatible with the VSS Hardware Provider installed with Plug-in for Exchange and SnapCenter Plug-ins Package for Windows.


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

    SnapCenter Server adds the host and then installs on the host the Plug-in for Windows and the Plug-in for Exchange if they are not already installed.

    Plug-in for Windows and Plug-in for Exchange must be the same version. If a different version of Plug-in for Windows was previously installed, SnapCenter updates the version as part of the installation.

    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 fully qualified domain name (FQDN).

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

    • Stand-alone host
    • Exchange DAG

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

    Run As name Select the Run As name that you created, or create the new Run As credentials.

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

    Details about Run As credentials, including the user name, domain, and host type, are displayed by placing your cursor over the Run As credential name you provided.

    Note: 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 enter a custom port number.
    The default port number is 8145.
    Note: If you manually installed the plug-ins with a custom port, you must specify the same custom port or else the operation fails.
    Add all hosts in the cluster or DAG This option must be selected when you add a DAG.
    Skip prechecks Select this check box if you already installed the plug-ins manually and do not want to validate whether the host meets the requirements to install the plug-in.

    The best practice is to have prechecks enabled.

  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, if different from the default.
    When you select Plug-in for Exchange, SnapCenter Plug-in for Microsoft SQL Server is deselected automatically. Microsoft recommends that SQL Server and Exchange server not be installed on the same system due to the amount of memory used and other resource usage required by Exchange.
  7. Click Next.
    If you have not selected the Skip prechecks check box, the host is validated to determine whether it meets the requirements to install the plug-in. If the minimum requirements are not met, the 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 in the SnapManager.PSModule.dll.config file. 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. 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 see the newly added host.
