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/gimiXX-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>
