Additional System Provisioning Options

The following lesson outlines additional system provisioning options.

Destroy System Replication

To start the SAP HANA system replication configuration process, choose ProvisioningSystem and AS. Choose the system on the left side of the screen and then choose Destroy System Replication. A roadmap appears, which guides you through the process of SAP HANA system replication destruction.

SAP HANA - Destroy System Replication: Delete Storage Volumes

In the Delete Storage Volumes step, you can choose the volumes to be deleted. Then finish the roadmap accordingly. After starting the SAP HANA system replication, you are forwarded to the Monitoring screen.

Destroy System

To start the destroy system process, choose ProvisioningSystem and AS. Choose the system on the left side of the screen and then choose Destroy System. The system needs to be in the not prepared state. The Destroy System option destroys systems managed by SAP Landscape Management. The Destroy partially provisioned System option destroys systems where provisioning failed, for example. A roadmap appears, which guides you through the process of system destruction.

Destroy System: Delete Storage Volumes

In the Delete Storage Volumes step, you can stop the relevant SAP system and select the volumes to be deleted. Then finish the roadmap accordingly.

Standalone PCA

To carry out several configuration steps on a system that was not provisioned by SAP Landscape Management, execute standalone post-copy automation (PCA). You have configured a suitable variant before in the target system. You have configured an RFC connection for the system. The system is enabled for Standalone PCA.

Standalone PCA: Process

To start the standalone PCA process, choose ProvisioningSystem and AS. Choose the system that you want to rename on the left side of the screen and then choose Standalone PCA. A roadmap appears, which guides you though the standalone PCA process.

Standalone PCA: Standalone PCA Base Step

Choose from the following entries from the dropdown:

  • Task List Execution

    When the homogeneous or heterogeneous system copy finishes, you can carry out several cleanup and configuration steps on the target system.

  • Export

    To prevent overwriting the target system configuration during system refresh, export the target system tables that contain configuration information before you start the system copy.

  • Import

    Import configuration data again after a system refresh into the target system.

If you select Enable PCA Profile Parameter, SAP Landscape Management sets the parameter ctc/allow_systemcopy_postconfig = 1 in DEFAULT.PFL and restarts the instances. The parameter Ÿctc/allow_systemcopy_postconfig = 1 is a prerequisite to execute PCA.

Standalone PCA: ABAP PCA

In standalone PCA, choose the task list that you want to execute. Choose the appropriate task list variant. If needed, modify the parameters within this view. Then finish the roadmap accordingly. After starting the standalone PCA process, you are forwarded to the Monitoring screen.

Provision Application Servers

SAP Landscape Management enables you to install application servers on an existing system. If you have configured the repository accordingly, enable the system for Application Server (Un-)Installation. Choose ConfigurationSystems. Choose the source system, and choose Edit.

In the Basic step, choose the source instance for the application server provisioning.

In the Application Server step, define the instance number for a new application server.

In the Hosts step, choose an existing host for the new application server. If you have configured a virtualization manager, choose to provision a new host.

In the Hostnames step, you can adjust the hostnames to your needs. Define the combination of virtual hostname and instance. Select Auto IP Address to assign an IP address automatically by using the range of IPs you specified when configuring the landscape. Choose a previously created network.

Mount points, which are mounted during Prepare, are shown in this step.

Note
The mount points step is only valid for AC-enabled.

In the SWPM step, select the created Release Configuration for installation. If requested, provide credentials.

In the Logon Groups step, if you have configured logon groups, choose to which logon group you want to add the new application server. Then finish the roadmap accordingly, After starting the application server provisioning, you are forwarded to the Monitoring screen.

Uninstall Application Servers

To start the uninstallation or application servers, choose ProvisioningSystem and AS. Choose the system on the left side of the screen and then choose Uninstall Application Servers. A roadmap appears, which guides you through the uninstallation process of application servers.

In the Basic step, choose the application server that you want to uninstall. Then finish the open roadmap steps accordingly. After starting the application server uninstallation, you are forwarded to the Monitoring screen.

Provision Diagnostics Agents

SAP Landscape Management enables you to install diagnostic agents on existing systems. You have configured the repository accordingly. Enable the system for Application Server (Un-) Installation. Choose ConfigurationSystems, choose the source system, and choose Edit.

In the Hosts step, the target system hosts are shown.

In the SWPM step, you can select the created Release Configuration for installation, and provide credentials. Then finish the roadmap accordingly. After starting the Diagnostic Agent provisioning, you are forwarded to the Monitoring screen.

Uninstall Diagnostics Agents

To start the uninstallation of diagnostic agents, choose ProvisioningSystem and AS. Choose the system on the left side of the screen and then choose Uninstall Diagnostics Agent. A roadmap appears, which guides you through the uninstallation process of diagnostic agents.

In the Basic step, select the diagnostics agents that you want to uninstall. Then finish the open roadmap steps accordingly. After starting the diagnostic agent uninstallation, you are forwarded to the Monitoring screen.

Provisioning Blueprints

To execute your blueprint, choose Operationsselect your systemopen Operations menuselect you button groupselect your Blueprint.

To schedule your provisioning blueprints, you have to create a operations template first. After you created the operation template you can schedule it from there.

Provide all information for the Scheduler.

Business Scenario

SAP system clones, SAP system copies, and SAP system refreshes can be simplified and automated using SAP Landscape Management. In this exercise, you will learn how to standardize and speed up SAP system copies, SAP system refreshes, as well as performing these operations in an end-to-end scenario. You will also learn how to destroy a SAP system copy.

Exercise Options
