Links Missing in the Topology Map

Problem

The topology map in the Paragon Planner desktop application GUI does not display any links for an archived network.

Solution

If the topology map does not display any links for an archived network, there can be two possible reasons: Either the backbone link (bblink.*) file is missing from the system, or the file is present in the system but is empty.

To check the status of the bblink.* file in the system, do the following:

1. Use your server credentials to log in to the primary node of Paragon Automation.

2. From the primary node, use the following command to obtain the name of the pod associated with the scheduler process (dcscheduler):

   content_copy zoom_out_map

   root@primary-node:~# kubectl get pod -n northstar|grep dcscheduler

3. Use the following command to log in to the dcscheduler pod:

   content_copy zoom_out_map

   root@primary-node:~# kubectl exec -it dc-scheduler-pod-name -c dcscheduler -n northstar -- bash

   In the command, dc-scheduler-pod-name is the name of the pod that you obtained in Step 2.

4. Navigate to the directory (/opt/northstar/data/archives/...) that contains the files corresponding to the archived network.

   The output displays the list of files present in the directory.

   Following is an example output that displays the size of the bblink.* file:

   content_copy zoom_out_map

   total 360
   drwxr-xr-x 1 root root     28 Aug 30 13:15 ./
   drwxr-xr-x 1 root root      1 Aug 30 13:15 ../
   drwxr-xr-x 1 root root      1 Aug 30 13:15 Log/
   drwxr-xr-x 1 root root     10 Aug 30 13:15 Report/
   -rw-r--r-- 1 root root    624 Aug 30 13:15 aclist.x
   -rw-r--r-- 1 root root    572 Aug 30 13:15 atconfig.x
   -rw-r--r-- 1 root root  24849 Aug 30 13:15 bblink.new
   

5. From the list of files displayed, check whether the bblink.* file is present and that the file size is greater than 0.

   If the file is not present, or if the file is present but the file size is 0, contact the Juniper Networks Technical Assistance Center (JTAC).
