Official Product Documentation: System Refresh Template Steps

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

Template StepDescriptionDependent stepsProperties
Create DirectoryCreates export folder and assigns the proper group and user to it.None
Change Profile PCA ExportAdds or changes the values of parameters in profile which is required for post-copy automation export.
Java Post System Copy Automation ExportExports the system configuration data before copy. Applicable only for NetWeaver Java Systems.
Post System Copy AutomationExportExports the system configuration data before copy. Applicable only for NetWeaver ABAP Systems-
Stop SAP InstanceStops source SAP instance.
Stop SAP InstanceStops source SAP central instance.
Stop DatabaseStops source database instance.
Unprepare DBUnprepares a database instance.
Unprepare SAP InstanceUnprepares SAP instance.
Unprepare SAP InstanceUnprepares SAP central instance.
Remove FirewallRemoves the firewall rule from the target host.
Prepare Clone Volumes

Prepares volumes in the

storage that will be

used for new system

after the system copy

process is finished.

This step is used only for provisioning storage based systems.

Mount ORA Redo Logs

Mounts a directory for

Oracle Redo logs.

Applicable only for systems

with Oracle database.

Clone Volumes With DB Backup Mode

Creates new volumes in a storage

that will be used for new system

after the system copy process is completed.

This step is used only for provisioning storage based systems.

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.

Umount ORA Redo Logs

Removes already mounted

directory for Oracle redo logs.

Applicable only for systems with Oracle database.

Finalize Clone Volumes

Makes final split of new volumes if it is required.

This step is used only for provisioning storage based systems

Update Instance Mount ConfigUpdates mount points into system configuration in LVM
STOPUsed only in scenarios, that provisioned host (VM based and storage based)
Stop SAP InstanceStops source instance.

Storage based systems:

VM provisioning systems:

Stop DatabaseStops source database instance.
Prepare DatabasePrepares source database for system refresh.
Finalize DatabaseThis operation will do necessary postprocessing steps after refresh of DB.
Clone Volumes - system copy provisioningOnly for storage based systems.
PROVISIONUsed only in scenarios, that provisioned host (VM based and storage based).
Start DatabaseStarts source database instance.

Storage based scenarios:

VM Provisioning scenarios:

Start SAP InstanceStarts source instance.
STARTUsed only in scenarios, that provisioned host (VM based and storage based.
WaitForResourceStateUsed only in scenarios, that provisioned host (VM based and storage based.
AddResourceUsed only in scenarios, that provisioned host (VM based and storage based).
Unprepare SAP InstanceUsed only in scenarios, that provisioned host (VM based and storage based.
Clear CacheClears cache of the operation system on the host.

Storage based systems:

VM based systems:

Prepare DBPrepares target database for system refresh.
Prepare SAP InstancePrepares target central instance for system refresh.
Prepare SAP InstancePrepares target instance for system refresh.
System Fencing

Modifys firewall rules in IP

tables of the operating

system (OS) to ensure

system is fenced and

decoupled from the network.

Create Users

Creates all needed users for OS access to new system.

They can be created in LDAP or locally.

Check Mounts

Checks if mount points created on OS of the hosts are working and file system is accessible.

Storage based systems:

VM based systems:

Change Profile PCA Enable

Adds parameters and values to the profile.

So the post-copy automation operation will be enabled.

Mount ORA Redo Logs

Mounts directory for Oracle Redo logs.

Applicable only for systems with Oracle Database.

ExecuteOperation/Host_AgentExecutes specified hook.
SAPINST rename

Calls Software Provisioning

Manager tool to perform a

rename of the copied system.

Then changes the files

ownership to target

user in target host.

System Fencing

Restores back the original rules in IP tables of the operating system to allow

access to the network again after the new system was created with different name and hosts.

Storage based systems:

VM based systems:

Start DatabaseStarts the database of the new system.
Start SAP Instance

Starts SAP central instance of the new system.

Start SAP Instance

Starts SAP instance of the new system

and must be executed for each application server instance.

Post System Copy Automation Import

This operation will Import the exported system configuration after the copy.

Applicable only for NetWeaver ABAP Systems.

Storage based systems:

VM based systems:

Java Post System Copy Automation ImportThis operation will import the exported system configuration after the copy. Applicable only for NetWeaver Java Systems.

Storage based systems:

VM based systems:

Java Post System Copy AutomationRuns post-copy automation to perform initial setup of the new system. Applicable only for NetWeaver Java system.
Remove DirectoryClears files and directories created from Software Provisioning Manager.

Storage based systems:

VM based systems:

Change Profile PCA Revert

Removes changes in profile files made from step

Change Profile PCA Enable

or set the default values to the parameter in profile

Storage based systems:

VM based systems:

Delete VolumesOnly for storage based systems. This step will delete old source volumes.
STOPUsed only in scenarios, that provisioned host (VM based and storage based).
DESTROYUsed only in scenarios, that provisioned host (VM based and storage based).
Umount ORA Redo Logs

Removes already mounted directory for Oracle redo logs.

Applicable only for systems with Oracle Database.

Activate SystemPerforms final enablement of system to be ready for monitoring in LVM.
