EndScan

  1. SDP Leaf Node provides API for EndScan workflow.

  2. The SDP Leaf Node accepts the command if :-

    1. Operational state of the SDP Leaf node is ON/OFF/INIT/STANDBY/ALARM

  3. The SDP Leaf Node rejects the command if :-

    1. Operational state of SDP Leaf node is FAULT/UNKNOWN .

  4. The following state requirements are applied for the command execution :-

    1. SDP Subarray is in ‘observation state’ SCANNING .

    2. SDP Subarray node is available .

  5. The command execution involves below key operations :-

    1. The command is then invoked on the SDP Subarray.

      • If SDP Subarray raises exception , command failure is reported as ‘RESULT_CODE - FAILED’ on Long Running Command Result attribute of the SDP leaf node.

      • If SDP Subarray accept command , the TMC SDP leaf node will wait for command completion.

  6. The SDP leaf node monitors the progress of command via the SDP sub-array node ObsState transitions .

    1. Command is successful when the SDP Subarray Node transitions to READY ObsState. This is reported as ‘RESULT_CODE - OK’ on Long Running Command Result attribute of the Subarray node.

    2. Command failure is reported in any of the below cases as ‘RESULT_CODE - FAILED’ on Long Running Command Result attribute of the Subarray node.

      • The SDP Subarray reports error event when command is invoked .

      • The command times out if SDP SubarrayNode does not transition to READY within the timeout period specified by CommandTimeOutDefault property specified in helm chart of the SDP Leaf Node .
