Registering a HANA host

Prerequisites

Ensure that the user has root privileges.
Ensure that you register the master server in a multihost system as the other hosts are automatically discovered when registering a HANA database. This prerequisite is applicable for HANA 2.0 version. For HANA 1.0 version, any active worker host can be used for database registration.
Ensure that the Public Key content is available in .ssh/authorized_keys file of the host user when the Authentication Type selected is Secure Key.

Procedure

Click the main menu and then click SAP HANA > Hosts.
On the master pane of the Hosts screen, click + Hosts

NOTE: For the first time host registration in RMC-SH, the Actions menu is not available.
In the Register Host screen, provide the following details:
- IP Address or Host Name - The IP address or the name of the HANA host. The hosts and RMC must be configured in the same domain.
- [Optional] Alias Name - An alias name for the HANA host.
- Username - The username to access the HANA database host that has root privileges.
- Specify the Authentication Type as either Password or Secure Key.
  For Authentication Type as Password, specify a password.
  
  For Authentication Type as Secure Key, verify that the Public Key content is correct.
- RMC Client Location - The shared location where the SAP HANA client is available. By default, the path is set to /hana/shared and cannot be blank.
- [Optional] Description - A short description about the database host.
Click Add.
NOTE:
- Refrain from using different login credentials for the same host configured at a remote appliance to manage HANA database configured with Remote Copy.
- SAP HANA host registration is dependent on the version of the installed OS version and not on the installed SAP HANA database.
- RMC-SH client installation does not check if SAP HANA database is installed on it. It only performs a check of the OS version.
- RMC resolves conflicts when you intend to perform a host registration by hostname or FQDN.
