Abort

  1. SDP Leaf Node provides API for Abort workflow.

  2. The SDP Leaf Node accepts the command if:

    1. Operational state of the SDP Subarray node is ON, OFF, INIT, STANDBY, or ALARM.

  3. The SDP Leaf Node rejects the command if:

    1. Operational state of the SDP Leaf node is FAULT or UNKNOWN.

  4. The command execution involves the following key operations:

    1. The command is invoked on the SDP Subarray.

      1. If the SDP Subarray raises an exception, command failure is reported as RESULT_CODE - FAILED on the Long Running Command Result attribute of the SDP Leaf Node.

      2. If the SDP Subarray accepts the command, the TMC SDP Leaf Node will wait for command completion.

  5. The SDP Leaf Node monitors the progress of the command via the SDP Subarray node ObsState transitions.

    1. Command is successful when the SDP Subarray Node transitions to ABORTED ObsState. This is reported as RESULT_CODE - OK on the Long Running Command Result attribute of the TMC SDP Subarray Leaf Node.

    2. Command failure is reported in any of the following cases as RESULT_CODE - FAILED on the Long Running Command Result attribute of the TMC SDP Subarray Leaf Node:

      1. The SDP Subarray reports an error event when the command is invoked.

      2. The command times out if the SDP Subarray Node does not transition to ABORTED within the timeout period specified by the CommandTimeOutDefault property in the Helm chart of the SDP Leaf Node.
