Viewing and Modifying Node Information

This section describes node parameters. You can also modify node information, such as node names.

Procedure

  1. Choose Cluster > Cluster > Hardware.
  2. In the lower part of the function pane, click the management IP address of the node that you want to view.

    The Node Details page is displayed.

    The Node Details page varies based on the node type.

  3. View the node details. Table 1 describes related parameters.

    This parameter can be modified only for newly-added nodes that have not been used.

    Slot

    Indicates the number of the slot where the node resides.

    [Value range]

    A slot number is an integer ranging from 0 to 4096.

    NOTE:

    This parameter can be modified only for newly-added nodes that have not been used.

    Management IP Address

    Indicates the management IP address of the node.

    Storage IP Address

    Indicates the storage IP address of the node.

    Role

    Indicates the role of the node.

    Maintenance Mode

    Indicates whether the maintenance mode of the node is enabled.

    NOTE:

    This parameter is available only when the node is a storage node.

    Processes

    Displays the processes on the node.

    NOTE:

    A process displayed in red indicates that the process is abnormal.

    Ports

    Displays ports on the node.

    NOTE:

    If a port is displayed in red, it is faulty or disconnected.

    Disks

    Displays disks on the node. You can click a disk icon to view its details.

    NOTE:
    • If a disk is displayed in red, it is faulty.
