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. 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. 272  IBM PowerHA SystemMirror V7.2.3 for IBM AIX and V7.2.2 for Linux Figure 7-3 Synchronous GLVM wizard menu  Create GMVG with Synchronous Mirror Pools Type or select values in entry fields.
