176 Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
To start with IP Quorum, complete the following steps:
1. If your IIBM Storwize V7000 is configured with IP addresses version 4, click Download 
IPv4 Application, or select Download IPv6 Application for systems running with 
IP version 6. In our example, IPv4 is the option, as shown in Figure 5-71.
Figure 5-71   IP Quorum Settings
2. Click Download IPv4 Application and the IBM Spectrum Virtualize generates an IP 
Quorum Java application, as shown in Figure 5-72. The application can be saved and 
installed in a host that is to run the IP quorum application.

3. On the host, you must use the Java command line to start the IP quorum application. 
Change to the folder where the application is located and run java -jar ip_quorum.jar.
I/O Groups
For ports within an I/O group, you can enable virtualization of Fibre Channel ports that are 
used for host I/O operations. With N_Port ID virtualization (NPIV), the Fibre Channel port 
consists of both a physical port and a virtual port. When port virtualization is enabled, ports 
do not come up until they are ready to handle I/O, which improves host behavior around node 
unpends. In addition, path failures due to an offline node are masked from hosts.
