Description

Occasionally deleting the BBSim OLT device does not result in the device being removed from VOLTHA. The OLT gets operstatus: UNKNOWN instead.

This can be seen in the voltha-system-tests job, which runs a periodic test using BBSim and VOLTHA images from the voltha-2.1 stabilization branch. Here are a couple of recent job runs that show this failure:

VOL-2029: Fix for OLT delete device. Don't call core to get child device as onu might not exist during delete of parent device. This would cause delays in delete and leaks with not releasing uniport resources. Add the uni port to device handler for OLT when the uniport resources are allocated while adding flows. Clear the uni port resources allocated during delete of olt device. Also ensure the resources for the PON port are deleted in the background since the olt device delete needs to finish within transaction timeout (8 seconds by default) and this can be time consuming.: Gerrit Review:
