Displaying Configuration Details

The shownode command enables you to list the configuration details for nodes and other hardware.

# shownode config

      multicast_install_disab

cp_ports:
   cp-n1:
      cp_type:       IPMI

You can also specify a node as a command argument to obtain the configuration details for those node or nodes:

# shownode config nodes n1
n1:
attributes:

cores_per_socket:       1
dirty:                  0
enabled:                1
host_names:
   Admin:
      device:           eth0
      gateway:
      hwaddr:           00:00:1a:18:fa:0b
      iftype:           Ethernet
      ifusage:          Admin
      ipaddr:           172.20.0.1
      name:             n1
      netmask:          255.224.0.0

Displaying the Nodes That Provide a Specified Service

Use the shownode servers command to display the node that provides a specific service to a given node. You do not need to be superuser to use this command.

This example shows how to determine which node provides the supermon service:

# shownode servers supermon
n3

The command output indicates that the node n3 supplies the supermon service:

You can also use the shownode servers command to display the node name of the node that provides a specific service to a given node:

# shownode servers ntp n3
n3

This command output indicates that the node n3 supplies the ntp service for itself.

Displaying Blade Enclosure Information

You can use the shownode command to provide information for the HP XC system with HP BladeSystems. With this command, you can:

Display the names of the blade enclosures and the nodes (server blades) within them.
List all the blade enclosures in the HP XC system and, for each, the nodes within them.
To list the nodes for a specified blade enclosure.
To list the blade enclosure for a specified node.
