| | 225 | |
| | 226 | This steps validates the ability to adjust the shared node allocation by following the instructions available in the [https://wiki.emulab.net/Emulab/wiki/SetupSharedNodes Setup Shared Nodes] page. The procedure executes the following: |
| | 227 | |
| | 228 | |
| | 229 | a. Use listresources at the InstaGENI GPO rack to find a dedicated node that is available for re-allocation |
| | 230 | b. Follow the instructions to add the node to the shared pool as defined at the [https://wiki.emulab.net/Emulab/wiki/SetupSharedNodes Setup Shared Nodes] page. |
| | 231 | c. Verify that the node becomes part of the shared pool via listresources component_id "exclusive" tag. |
| | 232 | d. Verify that no VMs are in use for the new shared node by checking that the tag "<emulab:node_type type_slots="100"/> ". |
| | 233 | e. Modify shared-nodes experiment to remove the node, (if not in use). |
| | 234 | f. Verify that the node is no longer part of the shared pool via listresources component_id "exclusive" tag. |
| | 235 | |
| | 236 | Here are details for each step that is executed: |
| | 237 | |
| | 238 | a. Listresources to find dedicated node available: |

| | 240 | {{{ |
| | 241 | $ omni.py listresources -a ig-gpo -o |

| | 255 | }}} |
| | 256 | |
| | 257 | According to the results above the 3 exclusive (aka dedicated) nodes are pc3, pc4, and pc5" and they are all available for use. The two nodes that are used as shared node (exclusive=false) are pc1 and pc2. Will add pc3 to the shared node pool. |
