Operations

Operations in SAP LaMa execute features to existing SAP systems and infrastructure. Some examples of

these operations are activating and deactivating SAP systems. With the

VMware Adapter for SAP Landscape Management there are three types of operations that you can perform

—

1

Forced Operations — Forced operations ignore system services and daemons on the target SAP system

and are generally non-graceful operations. The three forced operations that are supported are —

a

Forced Deactivate (Shutdown OS)

b

Forced Deactivation (Power Off)

c

Forced Suspend

2

Non-Forced Operations — Non-Forced operations execute on the target SAP system and generally get

executed in a graceful manner. The four Non-Forced operations that are supported are —

a

Activate

b

Deactivation

c

Deactivate

d

Suspend

3

Migrate Operation — The migrate operation allows you to migrate a SAP virtual machine onto another

host / network / datastore.

Forced Operations

To access these features, you should login to the SAP LaMa administrative console and navigate to the

Virtualization tab under Operations tab in the main menu bar.

‑2.  Forced Operations

There are three forced operations that are supported —

1

Forced Deactivate (Shutdown OS) — You use the Forced Deactivate option to shut down the operating

system.

2

Forced Deactivation (Power Off) — You use the Forced Deactivation option to power off the operating

system.

3

Forced Suspend — You use the Forced Suspend option to suspend the SAP system virtual machine.

Note   When you suspend a virtual machine (VM), the current system memory of the VM is written to

the disk. Then the VM is powered off. When you later restart the VM from vCenter Server Appliance,

the VM continues from exactly the same state as it was when it was suspended, including executing any

running transactions.

Non-Forced Operations

There are four Non-Forced operation features that you can execute —

1

Activate — You use this feature to power on the virtual machine, operating system and then the SAP

system.
