    Description

      (follow-up of SP-434)

      Show that an error / alert / alarm within the SDP can propagate over the Tango Interface with TM, using TANGO attributes as detailed in the control system guidelines.

      Develop interfaces to reset and restart processing (when errors are identified).

       

      Suggestion:

      Propagate error from EE through to the tango device (eg storage write error, SPEAD heaps dropped).

      Simplest option is to have the EE exit with a non zero exit code and capture that via k8s.

      Error provided on the Subarray device.

      (proposed) Objectives:

      An EE that exits with a non zero exit code results in an error in the tango device.

      Stretch: Extract richer details on the failure for the EE.

          • Should have - Items labelled as "Should have" are important but not necessary for delivery in the current delivery timebox. While "Should have" items can be as important as "Must have", they are often not as time-critical or there may be another way to satisfy the requirement so that it can be held back until a future delivery timebox.
