  • Maria suggested that we can include this check in upgrade step 4.
  • Maria also suggested that escalator should limit the scaling operation when upgrade is in progress to prevent failures due to the resource is in shortage.
  • Jianfei mentioned that after a smooth upgrade succeed, the operator could rollback to the previous version.

  • Jianfei suggested that we may include a use case to describe when upgrade is successful, but the Operator still have the opportunity to roll-back due to the performance issue.
  • Malla wondered how to detect failures dependent or independent
  • Jianfei mentioned that escalator should output some logs to help the operator to determine the failure type.
  • Jie suggested that the GUI should provide some information of the upgrade and roll-back in progress for checking.

  • Maria commented that the use cases should be more clear to the reader what is happened behind the scene, just click the button is not enough.
  • Uli commented that use cases need to identify the subsystem to be upgraded. I.e. whether the controllers or the network nodes etc.
  • Liyi asked Uli on what level of the subsystem that operator should specify.

  • Agreed to use the software dimensions of section 2.3 to derive requirements towards the upgrade actions and towards the software to be upgraded.

Essentially we need a way to coordinate the upgrade of different entities on the different hosts to ensure that there's no outage for the end-users.

  • Uli and Maria pointed out that ETSI documents were not accessible by non ETSI members, but putting URL links to the ETSI files on OPNFV Wiki would be OK.
