controller cannot perform NETCONF operations on node after it is re-attached through RESTCONF

Bug Resolved Done Maros Marsalek Ashwin Pankaj Tue, 28 Apr 2015 11:12:58 +0000 Wed, 6 May 2015 12:43:00 +0000 Wed, 6 May 2015 12:43:00 +0000 Helium netconf 0 1 <p>Attachment plugins.list has been added with description: List of jars in the plugin directory</p> <p>Tested multiple times on Helium-SR3 and Helium-SR1 and this works fine.</p> <p>Does your code re-retrieve current MountPoint instance after reconnect ? Because it looks like your code is keeping a reference to the original MountPoint after reconnect, which is not correct, since after each reconnect a new MountPoint instance is built and the old instance just does not work.</p> <p>If thats the case, you should listen to the changes of state for mounted node and react accordingly i.e. you cannot keep a reference to a MountPoint after a device is disconnected. Because if you do, you act as if there was no reconnect.</p> <p>This approach is demonstrated in coretutorials for ODL in subproject ncmount (it is built using current Lithium code but the concept stays the same).</p> <p>Decreasing priority by one level.</p> <p>Maros</p> <p>private MountInstance buildMountInstance(String node) </p> { InstanceIdentifier&lt;Node&gt; nodeInstance = buildNodeInstance(node); MountInstance mountInstance = mountService.getMountPoint(nodeInstance); LOG.info(nodeInstance.toString()); return mountInstance; } <p> private InstanceIdentifier&lt;Node&gt; buildNodeInstance(String node) </p> { NodeKey key = new NodeKey(new NodeId(node)); InstanceIdentifier&lt;Node&gt; nodeInstance = InstanceIdentifier .builder(Nodes.class).child(Node.class, key).toInstance(); return nodeInstance; } <p>(In reply to Ashwin Pankaj from comment #2)<br/> &gt; <br/> &gt; private MountInstance buildMountInstance(String node) </p> { &gt; InstanceIdentifier&lt;Node&gt; nodeInstance = buildNodeInstance(node); &gt; MountInstance mountInstance = &gt; mountService.getMountPoint(nodeInstance); &gt; LOG.info(nodeInstance.toString()); &gt; return mountInstance; &gt; } <p>&gt; <br/> &gt; private InstanceIdentifier&lt;Node&gt; buildNodeInstance(String node) </p> { &gt; NodeKey key = new NodeKey(new NodeId(node)); &gt; InstanceIdentifier&lt;Node&gt; nodeInstance = InstanceIdentifier &gt; .builder(Nodes.class).child(Node.class, key).toInstance(); &gt; return nodeInstance; &gt; } <p>Sorry - hit send button too soon.<br/> I always rebuild the node instance as shown above. Is that not enough ?</p> <p>Ok so this is a binding mount point issue.</p> <p>Fix submitted, needs to be retested:<br/> <a href="https://git.opendaylight.org/gerrit/#/c/19293/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/19293/</a></p> Development External issue ID 3076 External issue URL Rank 0|i02plz:
