Cluster management basics (cluster administrators only)

The cluster administrator can set up a new cluster by using the CLI Cluster Setup Wizard. After the cluster is created, the cluster administrator can display the cluster status and attributes, rename the cluster, or assign epsilon to another node in the cluster.

  • Displaying information about the nodes in a cluster
    You can display node names, whether the nodes are healthy, and whether they are eligible to participate in the cluster. At the advanced privilege level, you can also display whether a node holds epsilon.
  • Displaying cluster attributes
    You can display a cluster's unique identifier (UUID), name, serial number, location, and contact information.
  • Modifying cluster attributes
    You can modify a cluster's attributes, such as the cluster name, location, and contact information as needed.
  • Displaying the status of cluster replication rings
    You can display the status of cluster replication rings to help you diagnose cluster-wide problems. If your cluster is experiencing problems, support personnel might ask you to perform this task to assist with troubleshooting efforts.
  • Understanding quorum and epsilon
    Quorum and epsilon are important measures of cluster health and function that together indicate how clusters address potential communications and connectivity challenges.
  • What system volumes are
    System volumes are FlexVol volumes that contain special metadata, such as metadata for file services audit logs. These volumes are visible in the cluster so that you can fully account for storage use in your cluster.
