Creating a cluster administrative domain

In a high-availability solution, the cluster administrative domain provides the mechanism that keeps resources synchronized across systems and partitions within a cluster.

To create the cluster administrative domain, a user must have *IOSYSCFG authority and authority to the QCLUSTER user profile. To manage a cluster administrative domain, a user must be authorized to the CRG that represents the cluster administrative domain, the QCLUSTER user profile, and cluster resource group commands.

To create a cluster administrative domain using the PowerHA® graphical interface, complete the following steps:

  1. In a Web browser, enter http://mysystem:2001, where mysystem is the host name of the system.
  2. Log on to the system with your user profile and password.
  3. Click PowerHA from the IBM® Navigator for i window.
  4. On the PowerHA page, click on Cluster Administrative Domains.
  5. On the Cluster Administrative Domain page, select Create Administrative Domain ... from the Select Action menu.
  6. Specify the cluster administrative domain and click OK.
