Abort
=====

1. CSP Leaf Node provides API for **Abort workflow**.
2. The CSP Leaf Node **accepts the command** if :-

    A. Operational state of the CSP Leaf node is **ON/OFF/INIT/STANDBY/ALARM**
    B. CSP Subarray is responsive.

3. The CSP Leaf Node **rejects the command** if :-

    A. Operational state of CSP Leaf node is **FAULT/UNKNOWN/DISABLE** .
    B. CSP Subarray is not responsive.

4. The **command execution** involves below **key operations** :-

    A. **Delay values** are reset to **default values** and any **executing delay threads are stopped**. 
    B. The command is then invoked on the **CSP Subarray**.

        + If CSP Subarray **reports rejection/failure**, command failure is reported as **'RESULT_CODE - FAILED'** on Long Running Command Result attribute of the CSP leaf node.
        + If CSP Subarray **accept command** , the TMC CSP leaf node will wait for command completion.

5. The CSP leaf node **monitors the progress** of command via the CSP sub-array node **ObsState transitions** and the **long running command results**.

    A. Command is **successful** when the TMC Subarray Node transitions to **READY** ObsState. This is reported as **'RESULT_CODE - OK'** on Long Running Command Result attribute of the TMC CSP Subarray leaf node.
    B. Command **failure is reported** in any of the below cases as **'RESULT_CODE - FAILED'** on Long Running Command Result attribute of the TMC CSP Sub-array leaf node.

        + The CSP Subarray reports **'RESULT_CODE - FAILED'** on its Long Running Command Result attribute
        + The command **times out** if CSP SubarrayNode **does not** transition to **ABORTED** within the timeout period specified by `CommandTimeOutDefault` property specified in helm chart of the CSP Leaf Node .
