You can verify that the node object now contains attributes that are obtained during the node  discovery process (for example, hardware characteristics) and other xCAT attributes by  running the  lsdef  command (see Example 5-29).

The steps that are described in this section cover the stateless (diskless) installation. The  image includes only runtime libraries to keep the image size as small as possible. For more  information about a stateful image with full compiler support, see 5.7, “xCAT login nodes  (stateful)” on page 133. The network interface that is associated with the management network is known as a  primary  network interface  (or adapter). The network interfaces that are associated with other  networks are known as  secondary  (or additional)  network interfaces  (or adapters).
