How check the status of a Domain in the Testbed

Getting Started

1. Login into reserved domain

   Login into reserved domain

   During your approved time slot, you will be able to ssh into the console of the respective domain. A console is a dedicated machine that allows access to all resources in that domain.

   For example, to access the sandbox1:

   yourhost>ssh username@console.sb1.orbit-lab.org
   
   Using username "username".
   Authenticating with public key "xxxxxxxxx"

Checking the status

omf stat

This omf command is used to display the power status of the node/domain.

Usage: omf stat

username@consoles.outdoor:omf stat
Returns the status of the nodes in a testbed
Usage:
      omf-5.4 stat [-h] [-s] [-t TOPOLOGY] [-c AGGREGATE]
 
      With: 
      -h, --help                print this help message
      -s, --summary             print a summary of the node status for the testbed
      -c, --config AGGREGATE    use testbed AGGREGATE
      -t, --topology TOPOLOGY   a valid topology file or description (defaults to 'system:topo:all')
 
      Some Examples: 
                    omf-5.4 stat
                    omf-5.4 stat -s
                    omf-5.4 stat -t omf.nicta.node1,omf.nicta.node2 -c sb1
                    omf-5.4 stat -t system:topo:all -c grid

Individual nodes are identified in the output of stat command by their fully qualified domain name (FQDN). This establishes their "coordinates" and the "domain" to which they belong. Nodes in different domains typically can NOT see each other. Node can be in 1 of 3 states:

POWEROFF	Node is Available for use but turned off
POWERON	Node is Available and is on
NOT REGISTERED	Node is not Available for use

Example: omf stat on the outdoor domain

user@console.outdoor:~# omf stat -t all
