Official Product Documentation: System Clone Template Steps
The following template steps are executed during the system clone process with SAP Landscape Virtualization Management:
| Template step | Description | Dependent steps | Properties |
|---|---|---|---|
| Create Computer System Config | Creates a configuration for the new host in landscape virtualization management (LVM). | none | |
| Create System Config | Creates a configuration for the new system in LVM. | Create Computer System Config | |
| Stop SAP Instance | Stops source SAP instance. Relevant only for offline system clone. | Prepare Clone Volumes | |
| Stop Database | Stops source database instance. | Stop SAP Instance | |
| Finalize Database | This operation will do necessary postprocessing steps after cloning of DB. | Prepare DB | |
| PROVISION | Provisions a new host. Used only in scenarios, that provisioned host (VM based and storage based). | Finalize Database | |
| START | Activates/starts the host provisioned in the previous step.This step is used only in scenarios, that provisioned host (VM based and Storage based). | PROVISION | |
| WaitForResourceState | Waits for host to be available in the Virtualization Manager.This step is used only in scenarios, that provisioned host (VM based and Storage based). | START | |
| AddResource | Adds newly provisioned host into LVM configuration.This step is used only in scenarios, that provisioned host (VM based and Storage based). | WaitForResourceState | |
| Unprepare DB | Unprepares a database instance.This step is used only for provisioning VM based systems. | ||
| Prepare Clone Volumes | Prepares volumes in the storage that will be used for new system after “System Clone” process finished.This step is used only for provisioning storage based systems. | Create System Config | |
| Mount Ora Redo Logs | Mounts a directory for Oracle Redo logs.Applicable only for systems with database oracle. | Create System Config | |
| Clone Volumes With DB Backup Mode | Creates new volumes in storage that will be used for the new system after the system copy process is finished. In case the online clone scenario is executed. | ||
| Clone Volumes - system copy provisioning | Creates new volumes in storage that will be used for the new system after the system clone process is finished. In case the offline clone scenario is executed | Source System ID | |
| Umount Ora Redo Logs | Removes already mounted directory for Oracle redo logs. Applicable only for systems with Oracle database. | Clone Volumes With DB Backup Mode | |
| Post Clone Volumes | Checks if new volumes exist and exports paths for them in the storage system.This step is used only for provisioning storage based systems. | Source System ID | |
| Finalize Clone Volumes | Makes final split of new volumes if it is required.This step is used only for provisioning storage based systems. | Post Clone Volumes | Target System ID |
| Update Instance Mount Config | Updates mount points into system configuration in LVM. | Post Clone Volumes | Target System ID |
| Clear Cache | Clears cache of the operation system on the host. | Storage based systems:
VM based systems: | |
| Change Lookup | Modifys firewall rules in IP tables of OS to ensure system is fenced and decoupled from the network. | Clear Cache | |
| Prepare DB | Prepares source DB for system copy. | ||
| Prepare SAP Instance | Activates virtual hostname on a host, mounts volumes from storage (created in previous steps) on a host, and checks the status of instance and diagnostic agents.This step must be executed for each application server instance. | Change Lookup | |
| System Fencing | Modifys firewall rules in IP tables of OS to ensure system is fenced and decoupled from the network. | ||
| Check Mounts | Checks if mount points created on OS of the hosts are working and file system is accessible. | Target System ID | |
| Change Profile Parameters | Changes the values of parameters in profiles. | Check Mounts | |
| Change Profile StartUp Protection | This step must be executed for each application server instance. | ||
| Change Lookup | Restores back the original rules in IP tables of OS to allow access to the network again after the new system was created with different name and hosts. | ||
| Activate System | Performs final enablement of system to be ready for monitoring in LVM. | Change Profile StartUp Protection | Target System ID |
| Register Instance Agent | Forced register and start instance agent.This step must be executed for each application server instance. | Change Lookup | |
| System Fencing | |||
| Change Lookup | Restores back the original rules in IP tables of OS to allow access to the network again after the new system was created with different name and hosts. | System Fencing | |
| Start Database | Starts target SAP database. | ||
| Start SAP Instance | Starts target SAP instance.This step must be executed for each application server instance. | ||
| Remove directory | Clears directories used for temporary oracle logs.Applicable only for systems with database oracle. | ||
| Umount Ora Redo Logs | Removes already mounted directory for Oracle redo logs.Applicable only for systems with database oracle. | Clone Volumes With DB Backup Mode |
