Displaying the nodes in the cluster

You can display all the nodes in the cluster, their states, CPU load, and network load during the past 15 minutes.

If you use the Cluster> show currentload option, you can display the CPU and network loads collected from now to the next five seconds.

To display a list of nodes in the cluster

  1. To display a list of nodes that are part of a cluster, and the systems that are available to add to the cluster, enter the following:
    Cluster> show

    Command output includes the following information. See examples below.

    Node

    Displays the node name if the node has already been added to the cluster. Displays the IP address of the node if it is still in the process of being added to the cluster.

    Example:

    node_01

    or

    192.168.30.10

    State

    Displays the state of the node or the installation state of the system along with an IP address of the system if it is installed.

    See About the Veritas Access installation states and conditions.

    CPU

    Indicates the CPU load.

    pubethX

    Indicates the network load for the Public Interface X.

    bondX

    Indicates the network load for bond NIC X.

  2. For nodes already in the cluster, the following is displayed:
    Node     State     CPU(15 min) pubeth0(15 min)    pubeth1(15 min)
                        %      rx(MB/s) tx(MB/s)  rx(MB/s) tx(MB/s)
------   -------   ----------- -------- --------  -------- --------
snas_01  RUNNING     1.35       0.00     0.00      0.00     0.00
snas_02  RUNNING     1.96       0.00     0.00      0.00     0.00
  3. For the nodes that are being added to the cluster, for the nodes that are being deleted from the cluster, and for the nodes that is getting upgraded, the following progress is displayed:
    Nodes in Transition

Node/IP          Operation       State      Description
------           ---------       -----      -----------
192.168.30.11    Add node        FAILED     Installing packages
snas_03          Delete node     ONGOING    Removing node
snas_01,snas_02  Rolling upgrade ONGOING    Rolling upgrade phase 2

    Note:

    The add node and delete node operations cannot be performed at the same time.

  4. To display the CPU and network loads collected from now to the next five seconds, enter the following:
    Cluster> show currentload

    Example output:

    Node       State    CPU(5 sec)   pubeth0(5 sec)    pubeth1(5 sec)
                         %      rx(MB/s) tx(MB/s) rx(MB/s) tx(MB/s)
----       -----    ----------  -------- -------- -------- --------
snas_01  		RUNNING    0.26       0.01     0.00      0.01     0.00
snas_02  		RUNNING    0.87       0.01     0.00      0.01     0.00
snas_03    RUNNING    10.78      27.83    12.54     0.01     0.00

    Statistics for network interfaces are shown for each public interface available on the cluster nodes.
