LVM ProvisioningTemplate - Clone

Official Product Documentation: System Clone Template Steps

The following template steps are executed during the system clone process with SAP Landscape Virtualization Management:

Template stepDescriptionDependent stepsProperties
Create Computer System ConfigCreates a configuration for the new host in landscape virtualization management (LVM).

none

Create System ConfigCreates a configuration for the new system in LVM.Create Computer System Config
Stop SAP InstanceStops source SAP instance. Relevant only for offline system clone.Prepare Clone Volumes
Stop DatabaseStops source database instance.Stop SAP Instance
Finalize DatabaseThis 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 VolumesPrepares 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 LogsMounts 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 LogsRemoves already mounted directory for Oracle redo logs. Applicable only for systems with Oracle database.Clone Volumes With DB Backup Mode
Post Clone VolumesChecks 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 VolumesMakes final split of new volumes if it is required.This step is used only for provisioning storage based systems.Post Clone VolumesTarget System ID
Update Instance Mount Config Updates mount points into system configuration in LVM.Post Clone VolumesTarget 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 ProtectionThis 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 ProtectionTarget 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 InstanceStarts 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
