Troubleshoot Adding a Cluster

While attempting to add a cluster, a cluster already exists message is displayed.

Condition

After attempting to add a cluster via the Monitor tab, the message Cluster name already exists or Server name/IP name already exists is displayed.

Cause

Cluster name already exists indicates a cluster has already been added with the same Cluster Name.

Remedy

Retry adding the cluster using a unique Cluster Name.

  1. Click Manage Clusters.
    A dialog box appears where information about the cluster is entered.

    Figure 1. Manage Clusters
  2. For Cluster Name, enter a unique name for the cluster.

    The cluster name must be 20 characters or less.

  3. Continue filling in the rest of the information necessary to add the cluster.

Cause

Server name/IP name already exists indicates a cluster has already been added with the same Host name, but a different Cluster Name.

Remedy

Find the previously added cluster based on its hostname.

  1. Click Manage Clusters.
    HPC clusters that have been previously added are listed on the left hand side of the dialog box.

  2. Select a cluster by clicking on the name of the cluster.
    The form to the right of the list of clusters is populated with cluster information.
  3. Examine the value of Host for the cluster.
  4. Repeat the previous two steps until you find the cluster with a hostname that matches the hostname of the cluster you were trying to add.
    This is the cluster that you want to monitor.

Cause

If neither of the above remedies resolve the issue and the message Cluster name already exists or Server name/IP name already exists continues to display after attempting to add the cluster, a Manager may have revoked your access to the cluster.

Remedy

Contact your Control administrator.
