Adding hosts and installing plug-in packages on remote hosts

You must use the SnapCenter Add Host wizard to add hosts, and then install the plug-ins packages. The plug-ins are automatically installed on the remote hosts. You can add a host and install plug-in packages either for an individual host or for 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 role.
When installing a plug-in on a Windows host, if you specify a Run As account that is not built-in, or if the Run As user belongs to a local workgroup user, you must disable UAC on the host.
You should ensure that the message queueing service is running.
The administration documentation contains information about managing hosts.
Performing administrative tasks

Steps

In the left navigation pane, click Hosts.
Verify that the Managed Hosts tab is selected at the top.
Click Add.

On the Hosts page, perform the following actions:

For this field…	Do this…
Host OS	Select the type of host: Windows Linux Note: The Plug-in for SAP HANA is installed on the HDBSQL client host, and this host can be on either a Windows system or a Linux system.
Host name	Enter the communication host name. You must configure the HDBSQL client and HDBUserStore on this host.
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 your cursor over the Run As credential name that you provided. 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.
Check Fingerprint	Click Check Fingerprint to retrieve the fingerprint value. Verify the fingerprint, and then click Confirm Fingerprint. Note: Fingerprint verification is mandatory even if the same host was added earlier to SnapCenter and the fingerprint was confirmed.
Skip prechecks	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.

On the Installed plug-ins page, review the plug-in packages that are installed on the host.
For new deployments, no plug-in packages are listed.
On the Plug-ins to install page, select the plug-in package, and then specify the plug-in ports and installation path.
The Plug-in for SAP HANA is installed on the HDBSQL client host, and this host can be on either a Windows system or a Linux system.
For the SnapCenter Plug-ins Package for Windows, the default path is C:\Program Files\NetApp\SnapCenter. Optionally, you can customize the path.

For the SnapCenter Plug-ins Package for Linux, the default path is /opt/NetApp/snapcenter. Optionally, you can customize the path.
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. The disk space, RAM, PowerShell version, .NET version, location (for Windows plug-ins), and Java version (for Linux plug-ins) are validated against the minimum requirements. 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.
After fixing any validation errors, click Validate.
Review the summary, and then click Finish.
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.
