## 7.3.2 Synchronous configuration 

Before attempting to use the GLVM wizard, all the prerequisites that are listed in 7.2, “Prerequisites” on page 270 must be complete. Our scenario is a basic two-site configuration, with one node at each site, and an XD_data network with a persistent alias defined in the configuration, as shown in Example 7-2. 

# cltopinfo Cluster Name: GLVMdemocluster Cluster Type: Linked Heartbeat Type: Unicast Repository Disks: Site 1 (NewYork@Jess): repossiteA Site 2 (Chicago@Ellie): repossiteB Cluster Nodes: Site 1 (NewYork): Jess Site 2 (Chicago): Ellie #cllsif Adapter Type Network Net Type Attribute Node Jess boot net_ether_01 ether public Jess Jess_glvm boot net_ether_02 XD_data public Jess Jess_glvm boot  net_ether_02 XD_data public Jess Ellie  boot net_ether_01 ether public Ellie Ellie_glvm  boot net_ether_02 XD_data public Ellie Ellie_glvm_pers persistent net_ether_02 XD_data public Ellie 

Run smitty sysmirror  and select Cluster Applications and Resources →  Make Applications Highly Available (Use Smart Assists) →  GLVM Configuration Assistant Configure Asynchronous GMVG . 

The menu that is shown in Figure 7-3 opens. If not, then the previously mentioned prerequisites were not met, and you see a similar message to what is shown in Figure 7-4 on page 273.
