    To work with DASDs, you need to understand the following concepts: DASD-824

    Timeline (key events)

    1. T0: Monitoring alert — error rate spike on DASD-824.
    2. T0+5m: Automatic scaling attempted; insufficient to stop errors.
    3. T0+12m: On-call team acknowledged; began diagnostics.
    4. T0+30m: Root cause suspected in component C (resource exhaustion / config mismatch).
    5. T0+45m: Temporary mitigation applied — throttling & restart of C.
    6. T0+90m: Metrics returned to baseline; services recovered.
    7. T+24h: Post-incident checks and log collection completed.

    Risk Assessment & Residual Risk

    • Residual risk: Moderate until capacity testing and circuit-breakers are in place.
    • Likelihood of recurrence: Low-to-moderate without process changes.
    • Expected business impact if repeated: Intermittent outages and degraded customer experience.

    Use Cases and Applications

    Internal Process or Scheduler: In macOS, a background process called dasd (Duet Activity Scheduler Daemon) manages background tasks like file syncing and system updates. The "824" could potentially be a specific process ID (PID) or a version number within a localized system log. "DASD-824" most likely refers to the IBM Power
