Why are the nodes that I want not listed?

If the nodes that you need are not in the list, they might not meet specific requirements.

The Choose Nodes page provides a list of available nodes that are not already in use by another cluster. IBM® Systems Director discovered these nodes. All these nodes have the PowerHA® SystemMirror subagent software installed on them. Nodes must be unlocked through IBM Systems Director to be discovered and viewed on this page.

Ensure that all unlisted nodes that you want to include in the cluster meet the following requirements and conditions:
  • Use the Discover task in IBM Systems Director to discover all nodes in your subnetwork.
  • Use the Request Access task in the IBM Systems Director to unlock all nodes that have the status of no access.
  • Confirm that the nodes have the same AIX® version installed on them as the other nodes that you chose for this cluster.
  • start of changeConfirm that the nodes have the same version and edition of PowerHA SystemMirror installed on them as the other nodes that you choose for this cluster.end of change
  • Confirm that all the nodes share at least one storage disk among them to be used exclusively for the cluster repository. If you are using PowerHA SystemMirror 7.1.2 Standard Edition to configure a linked cluster with sites, the nodes for each site must have at least one storage disk in common among them.
  • Check the physical connection of the nodes to the listed nodes.
