How to Recover From an Interrupted Kernel Cage Dynamic Reconfiguration Operation

If the dynamic reconfiguration operation does not complete, perform the following steps to re-enable heartbeat timeout monitoring for that node and to reset the quorum vote count.

  1. If dynamic reconfiguration does not complete successfully, manually re-enable heartbeat timeout monitoring.

    From a single cluster node (which is not the node where the dynamic reconfiguration operation was performed), run the following command.

    # cluster monitor-heartbeat

    Use this command only in the global zone. Messages display indicating that monitoring has been enabled.

  2. If the node that was dynamically reconfigured paused during boot, allow it to finish booting and join the cluster membership.

    If the node is at the ok prompt, boot it now.

  3. Verify that the node is now part of the cluster membership and check the quorum vote count of the cluster nodes by running the following command on a single node in the cluster.
    # clquorum status
    --- Quorum Votes by Node (current status) ---
    
    Node Name       Present       Possible       Status
    ---------       -------       --------       ------
    pnode1          1             1              Online
    pnode2          1             1              Online
    pnode3          0             0              Online
  4. If one of the nodes has a vote count of 0, reset its vote count to 1 by running the following command on a single node in the cluster.
    # clquorum votecount -n nodename 1
    nodename

    The hostname of the node that has a quorum vote count of 0.

  5. Verify that all nodes now have a quorum vote count of 1.
    # clquorum status
    --- Quorum Votes by Node (current status) ---
    
    Node Name       Present       Possible       Status
    ---------       -------       --------       ------
    pnode1          1             1              Online
    pnode2          1             1              Online
    pnode3          1             1              Online
