This section explains how to list and get key information of the compute nodes already configured in sNow!

Compute Node List

In order to check the status of the compute nodes and other key information, execute the following command:

snow list nodes

This list provides detailed information about each compute node, including:

  • Name of the compute node
  • Status of the hardware
  • Status of the OS
  • Uptime
  • The image associated to the compute node
  • The template associated to the compute node
  • Date of the last deploy (if using deployment as provisioning mechanism).

Example:

snow list nodes atlas-[001-010]

Compute Node Show

The following command provides extensive information about the compute nodes, including:

  • Cluster associated
  • Image used to boot the OS
  • Template used to deploy the node(s)
  • Install repository
  • Console options
  • Time of the last deploy01
  • Proxy used during the deployment process. 
    snow show nodes <compute_node_name>

    Example:

    snow show node atlas-001
