Adding hosts and installing the Plug-in for VMware vSphere from the SnapCenter GUI

You can use the SnapCenter Add Host wizard to add vSphere hosts. The Plug-in for VMware vSphere is automatically installed on the specified host (which must be a Windows host) and is registered in the specified vCenter Server. You should use this method for installing the Plug-in for VMware vSphere on the local SnapCenter Server host or on a remote host.

Before you begin

For information on managing hosts, see the administration documentation.

Performing administrative tasks


  1. In the left navigation pane, click Hosts.
  2. Verify that Managed Hosts is selected.
  3. Click Add.
  4. On the Hosts page, specify the host on which you want to install the Plug-in for VMware vSphere:
    For this field… Do this…
    Host OS Select vSphere as the type of host.

    You must specify a virtual machine host that is using the Windows operating system.

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

    For the Plug-in for VMware vSphere, the default host name is the SnapCenter Server host. However, if you are installing the Plug-in for VMware vSphere on a dedicated host, then enter the FQDN or the IP address of that host.

    IP address is supported for untrusted domain hosts only if it resolves to the FQDN.

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

    You can specify one of the following:

    • IP address or FQDN of the stand-alone host
    • IP address or FQDN of the Windows Server Failover Clustering (WSFC)

    If the host is part of a sub-domain, you must provide the FQDN.

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

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

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

    Note: Run As credentials authentication mode is determined by the host type that you specify in the Add Host wizard.
    Attention: If the Run As account is not a built-in administrator or if the Run As user belongs to a local workgroup user, you must disable UAC on the host.
    Port Either retain the default port number or type a different port number.
    The default port number is 8144.
    Note: If you previously installed the Plug-in for VMware vSphere manually with a custom port, you must specify the same port. Otherwise, the operation fails.
    Skip prechecks Select this check box if you have already installed the Plug-in for VMware vSphere manually and do not want to validate whether the host meets the requirements for installing the plug-in.
  5. On the Plug-ins to install page, specify the vCenter information.
    1. Specify the host on which vCenter is installed.
      For the Plug-in for VMware vSphere, the default path is C:\Program Files\NetApp\SnapCenter. You can customize the default path if required.
    2. Specify the vCenter information.
      You should specify the requested vCenter information to enable the Plug-in for VMware vSphere to complete VMDK discovery.
  6. Click Next.
    If the Skip prechecks option was not selected, the host is validated to verify whether the host meets the requirements for installing the plug-in. The disk space, RAM, PowerShell version, .NET version, and location are validated against the minimum requirements. If the minimum requirements are not met, appropriate error messages or warning messages are displayed.

    After fixing the issue, you should click Validate to re-validate the requirements.

    If the error is related to disk space or RAM, you can either update 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 the other parameters, you should fix the issue, and then validate the requirements again.
    Note: In an NLB setup, if you are updating the web.config file, you must update the file on both the nodes.
  7. Review the summary, and then click Finish.
    You should monitor the installation progress. Refresh the Hosts page after a few minutes to see the newly added host.

    After a vSphere host is successfully installed, SnapCenter automatically registers the Plug-in for VMware vSphere with vCenter Server and installs the Plug-in for VMware vSphere web client on the vCenter Server.

    Note: The installation procedure does not validate the vCenter information that you provided before adding the host. If the vCenter information is not correct, the add host operation finishes, and a warning is displayed for the "Registering vCenter details with SnapCenter Plug-in for VMware vSphere" task. You can update the vCenter information for that host from the Hosts page.


When you select a vSphere host type, the SnapCenter Server performs the following during the installation:

The SnapCenter Server establishes communication with the vCenter Server, using the vCenter information that is provided on the Plug-ins to install page of the wizard.
