Test Plan Steps

Step 1. Identify processes and versions

A site administrator enumerates processes on each of the server host, the Control VM, the VMOC VM, etc. and an experimental node configured for OpenStack, which listen for network connections from other nodes, identifies what version of what software package is in use for each, and verifies that we know the source of each piece of software and could get access to its source code.

First get supported versions for the AM API and verify access to resources:

$ omni.py getversion -a https://clemson-clemson-control-1.clemson.edu:5001

18:45:30 INFO     omni:  ======================================================

There is no aggregate version information (ticket #115)

Then verify that resources are available for experimenters:

$ omni.py listresources -a gram  -o

the following are major services for OpenGENI:

  • gram-am - the aggregate manager that handles AM API calls for resources
  • gram-vnoc - VMOC controller that manages OpenFlow traffic for switch(es) and experimenter controller(s).
  • gram-ctrl- Default controller that performs layer 2 MAC to port learning.
  • gram-mon- Data collection, not sure how it fits in to current plan.

On the Clemson rack, the OpenGENI software is installed in /home/gram/gram on the control node named "clemson-clemson-control-1" (130.127.88.98) and the OpenGENI services listed above are started by scripts in the /home/gram/gram/src/services directory:

$ ls -ltr /home/gram/gram/src/services
total 24
-rwxrwxr-x 1 gram gram 1802 Apr  8 12:21 gram-vmoc.conf
-rwxrwxr-x 1 gram gram 1499 Apr  8 12:21 gram-mon.conf

Description: GRAM installation package

Step 2. Review control network configuration

A site administrator reviews the configuration of the rack control plane switch and verifies that each experimental node's control and console access interfaces are on the expected VLANs. According to Details on Clemson OpenGENI Rack Installation and Configuration document interfaces are configured as follows on the OpenGENI nodes:

  • eth0: Control network configured for 10.10.8.0
  • eth1 : Data plane network configured for 10.10.5.0
  • eth3 : Management network configured for 10.10.6.0

Subnet masks for network are not listed.
