OMNI Commands for slice workflow

  • Create slice
    $ omni.py -c omni_config -a https://geni.renci.org:11443/orca/xmlrpc createslice <slice name e.g. tutorialXX>
    
  • Create sliver in ORCA
    $ omni.py -c omni_config -a https://geni.renci.org:11443/orca/xmlrpc -n createsliver <slice name> two-node.rspec
    
  • Poll for sliver status
    $ omni.py -c omni_config -a https://geni.renci.org:11443/orca/xmlrpc sliverstatus <slice name>
    
  • After sliver status turns 'ready', list resources in the slice
    $ omni.py -c omni_config -a https://geni.renci.org:11443/orca/xmlrpc listresources <slice name>
    
  • Using IP addresses login to node(s)
    $ ssh -i ssh/orcatuXX-key root@<ip address from manifest>
    
  • Delete sliver/slice
    $ omni.py -c omni_config -a https://geni.renci.org:11443/orca/xmlrpc deletesliver <slice name>
