Why are the nodes that I want not listed?

If the nodes that you need are not in the list, ensure that they meet the following requirements:

  • Use the Discover task in IBM® Systems Director to discover all nodes in your subnet.
  • Use the Request Access task in the IBM Systems Director to unlock all nodes that have the status of no access.
  • The level of AIX® and the level and edition of the PowerHA® SystemMirror installed on those nodes are the same as the other nodes you have chosen for this cluster.
  • All appropriate PowerHA SystemMirror licensed programs ([standard_LP]) are installed on those nodes.
  • All nodes share at least one storage disk.
  • Check the physical connection of the nodes that are not known to cluster nodes.

For more information about adding nodes to a cluster, see the Adding nodes to a cluster topic in the AIX Information Center.
