Update topology script to retrieve hwsku from minigraph if hwsku information is not available in config_db. Fix clean up of interfaces in msft_multi_asic_vs hwsku topology script. - Why I did it When bringing up multi-asic VS switch, topology service is started during boot up. Topology service starts a shell script which runs the topology script present in /usr/share/sonic/device// directory. To invoke hwsku specific script, the topology script tries to retrieve hwsku information from config_db. During initial boot up config_db might not be populated. In order to start topology service before config_db is updated, update topology script to get hwsku information from minigraph.xml if it is available. This will be helpful to bring up multi-asic VS testbed by loading minigraph and starting topology service. - How I did it Update topology.sh script to retrieve hwsku information from minigraph.xml. Fix clean up function on msft_multi_asic_vs toplogy script. - How to verify it single-asic VS - no change; topology service is only enabled for multi-asic VS. multi-asic VS - Bring up multi-asic VS image, copy minigraph to vs image, start topology service. Topology service should be successful. to test clean up function fix, start topology service - make sure interfaces are created and moved to the right namespaces. stop topology service - make sure namespace do not have any interface and all front end interfaces are present in default namespace.
