note: >-
  Avamar layers two distinct error surfaces: HTTP-level errors returned by the REST API, and numeric
  Avamar event/error codes attached to backup, restore and move activities. The authoritative numeric
  registry is not published as a single machine-readable file — Dell distributes it as KB articles and
  ships the complete catalog on the appliance itself. Only entries verified in Dell documentation are
  recorded below; the numeric catalog is referenced rather than reproduced.
api_error_envelope:
  transport: HTTP status code
  body_field: message
  media_types:
  - application/json
  - application/xml
  detail: >-
    For a synchronous call the HTTP response code indicates the operation's final status; when the
    operation fails the response body includes a `message` element describing the reason. For an
    asynchronous call the failure surfaces on the task resource as a terminal `state` of ERROR,
    CANCELED or ABORTED.
  troubleshooting: >-
    Dell's documented failure-triage procedure is to examine the HTTP status code returned by the
    Avamar REST API server and then examine the Avamar REST API log.
async_failure_states:
- state: ERROR
  meaning: The asynchronous operation failed.
- state: CANCELED
  meaning: The asynchronous operation was canceled before completion.
- state: ABORTED
  meaning: The asynchronous operation was aborted.

retryable_error_class:
  setting: move.queue.error.codes
  detail: >-
    Avamar Client Manager treats a specific set of numeric error codes as retryable for client move
    tasks — a failed move is queued for retry only when its failure produces one of these codes. The
    default list is the closest thing Dell publishes to a machine-readable transient-error class.
  default_codes:
  - 22271
  - 22280
  - 22282
  - 22295
  - 30006
  - 30012
  - 30016
  - 30017
  - 30019
  special_values:
    none: never queue a failed move task for retry
    empty: queue every failed move task for retry
  retry_policy:
    move_retry_attempts: 24
    move_retry_frequency_minutes: 120
