Which two data sources do you use to explain this message? (Choose two.)
To explain the 'long CP' (Consistency Point) message in the EMS logs, you would use data sources that provide detailed performance and system insights. The Performance Archive offers historical performance data and can help identify trends or issues that might have caused prolonged consistency points. Active IQ Unified Manager is valuable for monitoring and managing the health and performance of your storage environment. It can provide in-depth analysis and alerts regarding system performance, helping you to understand potential issues impacting the aggregate AG1_NTAP_PROD. Together, these sources provide comprehensive data needed to diagnose the message.
solution: Failing disks can potentially cause poor write performance and long CPs. Trigger a Performance archive from the cluster during the timeframe, or collect a statit data collection from the node shell.
