Displaying information about the appliance node

Use CLI or web console to view information about nodes in Integrated Analytics System.

About this task

A node can be defined by its state and status. The node state determines its use in the system, not its health. Node state can be one of the following:
  • ENABLED - the node is used to run appliance applications
  • DISABLED - the node is not used to run appliance applications
  • ENABLING - node enablement is in progress
  • DISABLING - node disablement is in progress

You can also check the status of the node, which is its health, for example, OK, or WARNING.

Procedure

  • To display node state, use the ap node command: 
    ap node
+-----------------+----------+-----------+-----------+
| Node            |    State | Monitored | Is Master |
+-----------------+----------+-----------+-----------+
| hadomain1.node1 |  ENABLED |       YES |       YES |
| hadomain1.node2 |  ENABLED |       YES |        NO |
| hadomain1.node3 | DISABLED |       YES |        NO |
+-----------------+----------+-----------+-----------+

  • To display information about the mapping of multiple logical nodes (MLNs) and logical ports, as well as MLN status, use the ap ds command: 
    ap ds

  • You can also use the web console to view node information. Click System > Monitor > Hardware
    There is a graphical overview of the appliance. You can view all nodes with their physical location in the rack. Next to a node there is an icon representing possible alerts. You can view details in the Nodes section on the right side.
