Installation process overview SAP Landscape Virtualization Management (SAP LVM)

In this document i will give you an overview of the installation process, the requirements and

initial configuration of SAP LVM.

You can find additional detailed information in the Configuration and Deployment section of

our online help : http://help.sap.com/nwlvm and in our Best Practices guide.

You can click on any of the pictures below to get a larger view !

Lets start with an overview of the main components:

SAP LVM is a Java based add-on that is installed on a Java Application Server

We use the SAP Host Agent to connect and control SAP Instances

We use adapters for storage and virtualization to connect to the infrastructure and enable copy processes

This picture gives you an overview of the steps that are required to complete the whole process

The initial system setup and basic configuration are always required and will enable you to do basic

management functions like start/stop ,system overview , scheduling and so on.

If you want to use the system provisioning features you also need to complete the infrastructure config

In the extended configuration section i will show you how to adapt LVM to your environment

Lets get started, the next steps are all done on the System where you install SAP LVM

Now we move to the hosts where your SAP Systems are running

SAP LVM requires the SAP Host Agent to connect to the SAP systems in your landscape and to control them

Please make sure that your SAP Host Agent is on the latest patch level to avoid problems

Now we are moving to the SAP LVM management GUI. The default URL for logging in, should look like this

http://lvmhost.domain:50000/lvm

We start with the configuration of a pool. Pools is a way to group systems. Since it is possible

to run functions like start/stop both on system and pool level you should group systems in a way that allow

you to manage them in an easy way. E.g. productive vs. test systems

In the next step you add your hosts and systems to LVM. This is done via the "Discover" button under the

"Hosts" and "Systems" section of the "Configuration" tab.There are a couple of ways to discover your

hosts and systems:

Detect using host and instance agent: Here you can give a host name or ip address or a range of ip-addresses

and LVM will try to connect and use the SAP Host Agent to discover which instances are installed.

Virtualization Manager: LVM will connect to the virtualization management software and retrieve the list of

hosts and will connect to SAP Host Agents to discover which instances are installed.

Landscape scanner: The Landscape Scanner is a background process that continuously scans the known

Network for new systems and will notify you if it finds something. You can then decide if you want to add the

found systems to SAP LVM.

System Landscape Directory: LVM will connect to the SLD and get the configuration information from there

This will only work if your SLD accurately represents your current Landscape.

For system discover you use the same procedure.

During System configuration, LVM will show you the configured filesystems.

It is very important to make sure that this information is accurate. LVM uses

this information to determine which filesystems to copy.

At this stage you have a configured SAP LVM and can start to use it for basic management functions.

Next we will look into the Infrastructure Configuration needed for an End to End system copy process

Networks are a way to group your different Network segments. You have to configure some parameters

like ip range, broadcast address and so on. Each system needs to be configured for one of your networks

The storage manager is needed if you want to use a "storage based cloning" procedure. The storage

adapter connects to the storage management Software and controls the replication of the data volumes

needed for a clone/copy/refresh process. If you are using virtualization and your data resides on virtual disks

you configure the virtualization adapter under "Virtualization Managers"

During a copy process, LVM is able to create the users needed for the copied system. For this to work

you need to configure the user management service. We support LDAP,NIS,Active Directory. It is possible

to leave this out, but you then need to manually pre-configure the users needed in your user managment

system.

Similar to the user management , LVM can handle the assignment of virtual hostnames/ip addresses

automatically and you can configure the DNS servers here. Here it is also possible to leave it out, but

you need to manually manage the relationship between hostnames and ip addresses.

System rename is needed as part of the overall process and requires a so called release configuration. This

is a SWPM specifically for a release/platform combination.You can download SWPM as part of the

SL Toolset.Software Logistics Toolset (SL Toolset) – SAP Help Portal Page You should create a shared

filesystem that can be mounted on all of your hosts. LVM will automatically mount this  filesystem on the

target host to execute the system rename. In this configuration you point LVM to the shared filesystem.

The JAVA Post Copy Automation is required to rename a JAVA based instance. This is a standalone tool

that you install on a Linux or Windows based server in your Landscape. It runs a web service that LVM uses

to make the necessary changes on the JAVA stack

The ABAP Post Copy Automation is installed inside your ABAP source system. Depending on the release

level of your source system most of the content will already be installed. Please check the SAP notes to see

what you need to do to get it to the most current version.
