Node cannot be added to the GPFS cluster

 

There is an indication leading you to the conclusion that a node cannot be added to a cluster and steps to follow to correct the problem.

That indication is:

  • You issue the mmcrcluster or mmaddnode command and receive the message:
    6027-1598
    Node nodeName was not added to the cluster. The node appears to already belong to a GPFS™ cluster.
Steps to follow if a node cannot be added to a cluster:

  1. Run the mmlscluster command to verify that the node is not in the cluster.
  2. If the node is not in the cluster, issue this command on the node that could not be added:
    mmdelnode -f
  3. Reissue the mmaddnode command.
