Add a node to a device domain

A device domain is a subset of nodes in a cluster that share device resources.

Before a node can be added to the recovery domain for a device cluster resource group (CRG), the node must be first defined as a member of a device domain. All nodes that will be in the recovery domain for a device CRG must be in the same device domain. A cluster node can belong to at most one device domain.

To create and manage device domains, you must have Option 41 (HA Switchable Resources) installed and a valid license key must exist on all cluster nodes that will be in the device domain.

Using iSeries™ Navigator

To add a node to a device domain in iSeries Navigator, follow these steps:

  1. In iSeries Navigator, expand Management Central.
  2. Expand Clusters.
  3. Expand the cluster that contains the node you want to add to the device domain.
  4. Click Nodes.
  5. Right-click the node you want to add to the device domain, and select Properties.
  6. On the Clustering page, specify the name of the device domain you want to add the node to in the Device domain field.

Using CL commands and APIs
