## 6.10 Example 2: Setting up one ROHA cluster (with On/Off CoD) 

## 6.10.1 Requirements 

This section describes the setup of one ROHA cluster example. 

We have two Power 770 D model servers in one Power Enterprise Pool, and each server has an On/Off CoD license. We want to deploy one PowerHA SystemMirror cluster and include two nodes that are in different servers. We want the PowerHA SystemMirror cluster to manage the server’s free resources, EPCoD mo bile resources, and On/Off CoD resources automatically to satisfy the application’s hardware requirement before starting it. 

## 6.10.2 Hardware topology 

Figure 6-41 shows the server and LPAR information of example 2.

The topology includes the following components for configuration: 

GLYPH<SM590000> Two Power 770 D model servers that are named P770D-01 and P770D-02. 

GLYPH<SM590000> One Power Enterprise Pool with four mobile processors and 100 GB of mobile memory. 

GLYPH<SM590000> Each server enabled the On/Off CoD feature. 

GLYPH<SM590000> PowerHA SystemMirror cluster includes two nodes, ITSO_S1Node1 and ITSO_S2Node1.
