Adding Hosts

You use this procedure to add hosts to the landscape and make them available for performing operations in SAP Landscape Management.

Prerequisites

You have configured the following:

Context

You can add hosts in the following ways:

Scenario	Source	Description
Find hosts available in the landscape and add them to SAP Landscape Management.	Detect using host and instance agents	SAP Landscape Management directly communicates with the SAP Host Agent to retrieve the host information from the landscape. The hosts found are directly configured in SAP Landscape Management.
	Detect on managed hosts	SAP Landscape Management searches for the new instances available on hosts already configured.
	SAP Landscape Management Landscape scanner	You can set the automatic landscape scanning attribute when configuring SAP Landscape Management using the configuration wizard or when configuring the engine settings. The landscape is automatically scanned for newly added hosts and instances based on the attribute set. The number of detected hosts is shown in SAP Landscape Management under Overview.
	Virtualization Manager	SAP Landscape Management searches for new hosts available in the virtualization manager.
	Local System Landscape Directory	SAP Landscape Management retrieves host details from the local System Landscape Directory using a pre-configured System Landscape Directory destination.
	Remote System Landscape Directory	SAP Landscape Management retrieves host details from the remote System Landscape Directory by accessing it through the System Landscape Directory URL.
Import the host configuration data	XML file	You reuse the host configuration data by importing the configuration data to SAP Landscape Management.

Procedure

Choose Configuration Hosts.
Choose Discover.
From the Source dropdown box, choose the desired source.

Recommendation Choose Detect Using Host and Instance Agent.

Note If you choose Detect Using Host and Instance Agent as the source and X.509 Client Certificate as the authentication type, all public and private keys must be stored in the key storage. To configure the keys, choose Goto Certificates and Keys: Key Storage.
In the Find dropdown box, specify whether you want to find instances or hosts, or both.
Depending on the source chosen, enter any other information as required.
Depending on the source chosen, choose Detect or Retrieve.
Note
- It is not always possible to find all instances that belong to a system in one step. For example, it is not possible to find a TREX instance that belongs to a given system by running the detection process for a single SAP Host Agent. Therefore, if you want to detect a complete system set, you may need to execute the detection process for multiple SAP Host Agents.
- If problems occur during detection, choose View Detection Issues.
To configure the hosts detected using the auto-assign facility, choose Next.
Save your entries.

Results

The hosts detected are added to an existing pool and are available to perform operations without any further configuration.
