1

Select the type of clone that you intend to create — either Linked Clone or Full Clone. You do

this by selecting appropriate value in the Value drop down list.

Note  

n

A Linked Clone creates a target system that has a file link to the original source system.

This reduces the utilized storage for the target system. It is most commonly used in

development and sandbox systems. Linked Clones creation completes substantially faster

than Full Clones.

n

A Full Clone creates a target system that has the same disk structure and size as the source

system. There is no link between the source and target systems. Full clones are most often

used to create production systems and /or systems that can be exported to be used in

other datacenters.

2

Select the Guest Customization specification for the target Clone System.

n

Guest Customization specifications are created in the VMware vCenter Server and are

made available via the VMware Adapter for SAP Landscape Management. You need to

create a guest customization specification in order to clone a system (

GUID-B2125827-

E0DE-4E79-A04C-1316E81B788E#GUID-B2125827-E0DE-4E79-A04C-1316E81B788E

)

n

Work with your VMware Administrator to create Guest Customization specifications if

none are present in the SAP LaMa.

n

Note that DHCP customization specifications may cause an inconsistent /etc/hosts file

contents in the target system. PROMPT customization specifications is a more reliable

option. Refer to section 

“Known Issues,”

 on page 53 for more information.

Click Next tab in the menu bar of the Define Virtual Host window.

‑22.  Define Virtual Host - Network Adapters

In the fourth step called Network Adapters, you select the target network for the network adapters

of the target clone system.

Note   If you are changing the virtual network at this step, ensure that the network is reachable

from the LaMa too. This is required for the LaMa to manage the target system

e

‑23.  Define Virtual Host - Host Names

The next step is Host Names. Changing the virtual network should be considered on the Host

Names step in order to assign consistent IP addresses and hostnames from the new network. There

is no input required for the Host Names step. Click Next tab in the menu bar of the Define Virtual

Host window to continue.

f

You are now at the last Summary step. In this step of the Define Virtual Host window in your

browser, you can review the various settings that you have chosen so far. Use the Previous tab in

the menu bar to go back and make appropriate changes to the settings if needed. If you are OK

with the settings, Click on the Define tab to finish defining the new virtual host settings.

Click on Next tab to proceed to the third step in the System Cloning window. In this step called Host

Names , you choose a different network for each component of the target SAP system. If the host is not

configured as an adaptive instance you will see warning messages. You need to ignore these warnings

by Clicking the Ignore Warnings for this step button.

Click on Next tab in the menu bar of System Cloning window to go to the next step called Consistency.

In this step you choose the database consistency method. Depending on what state the database is in,

you can choose one of the following options by Clicking on the appropriate radio button —

a

Online(Backup Suspend IO Mode and a Timeout value) — You use this option typically for

cloning production systems to prevent system outages. You need to provide a Timeout value in

seconds to ensure that consistency is done in a timely manner.

b

Offline(Stop and Restart System) — When you select his option the SAP LaMa will stop the system,

make a clone of the system and then restart the clone.

c

Offline(Database already stopped) — You select this option when the database is already stopped.

d

Database was stopped during system snapshot — You select this option when the database has

already been snapshotted prior to this process starting.

e

Scheduled execution of cloning step — You use this option to schedule the cloning operation at a

specific date/time of your choice. You need to input the date and time when you want to schedule

the cloning operation. This option is useful, for example if you want to ensure that the current

ongoing system activity is not impacted.

Click the Next tab after selecting one of the above mentioned options.
