Orchestration Management 13-3
Orchestration Types
The Active System Manager software facilitates the template owner with the ability to specify the
Orchestration on the basis of three different reservation states where Orchestrations can be executed.
Table 13-1 lists and describes the various Orchestration types based on reservation states.
Table 13-1 Orchestration Types
Orchestration Type Description
Setup The Setup Orchestrations can be defined per template, and each template can
contain a maximum of one Setup Orchestration. When a template with a Setup
Orchestration is scheduled, and when the session attains a Setting Up
reservation state, the Active System Manager software execution service
implements the Setup Orchestration automatically. The custom operations
defined in the Setup Orchestration steps run one after the other; thus, avoiding
manual intervention.
During a Setup Orchestration, the following steps effect in sequence:
1. The devices are powered on.
2. The device connectivity is checked.
3. Resource-level scripts are executed.
4. Reservation scripts are executed.
5. The Setup Orchestration is executed.
Note: Setup Orchestrations are executed after the generation of reservation
scripts.
On-demand The On-Demand Orchestration enables the ability to initiate an Orchestration
execution in a running Active System Manager session, as needed.
On-Demand Orchestration executes one at a time in the running session. Before
doing so, the Active System Manager software validates the Orchestration for any
missing or removed device in the template. For more details, see the “Executing
Orchestration” section on page 13-16.
Teardown The Teardown Orchestration can be defined per template where each Template
can contain a maximum of one Teardown Orchestration. When a template with a
Teardown sequencing is scheduled and goes into a Clean Up state, the Active
System Manager execution service implements the Teardown Orchestration as
per the custom operations defined in the Orchestration steps.
During a Teardown Orchestration, the following steps effect in sequence:
1. Teardown Orchestration is executed.
2. Reservation Teardown scripts are executed (default or user-defined, as
available).
3. Resource-level Teardown scripts are executed.
4. Connected devices are released.
5. On devices are powered off.
The template owner has the ability to specify Orchestration on the basis of
reservation states for the custom Orchestration constructs, using a drag-and-drop
method.
Note On creation, all Orchestrations are of the On-Demand Orchestration type. However, you can easily
change them into a Setup Orchestration or a Teardown Orchestration, and vice-versa, in the
Orchestration view.
