## 4.3 CTN reconfigurations 

In this section we provide examples of CTN reconfiguration operations: 

GLYPH<SM590000> Adding a server to a CTN and re-assigning server roles 

GLYPH<SM590000> Splitting a CTN 

GLYPH<SM590000> Merging two CTNs 

## 4.3.1 Adding a server to an existing CTN and re-assigning roles 

In this sample we add the System MUSCA to the existing CTN CTN_New . MUSCA is part of the inactive CTN CTN3 and is therefore ready to be added to CTN_New . 

Note:  A server must be part of a CTN (active or inactive) to be added to an existing CTN. 

We select the CTN ID CTN_New  to be the receiving CTN. Then we click on “Add systems to CTN” under STP ACTIONS. A window with all available Systems and their corresponding CTNs is shown. In our case only MUSCA CPC is available. We select MUSCA by clicking on its name and then continue (NEXT), as shown in Figure 4-16.

A window which shows the target configuration will then be shown. We accept this by clicking APPLY. The next window provides an overview of the system(s) that will join. 

The message shown in Figure 4-17 on page 107 informs that the CTN ID for the server selected to join the existing CTN will change to match the target CTN ID.
