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.
