The alert indicates that Oracle Automatic Storage Management Cluster Health Check (AMCHC) or Oracle Autonomous Health Framework (AHF) has detected a new hardware, configuration, or disk failure within your Oracle Grid Infrastructure environment.
To resolve the issue, follow these steps: asm health checker found 1 new failures updated
The ASM Health Checker runs continuously within the background processes of an ASM instance (specifically managed by components like the and Global Enqueue Service (LMON) ). The alert indicates that Oracle Automatic Storage Management
user wants a detailed article about the ASM Health Checker notification "found 1 new failures updated". This requires explaining what ASM Health Checker is, the meaning of the notification, common causes, troubleshooting steps, and its role in wider monitoring. I will follow the search plan, opening the initial result to understand ASM Health Checker basics, then performing the specified searches. initial open of the Oracle documentation failed. The search results provided some useful links. The search for "ASM Health Checker found 1 new failures updated" yielded a potentially relevant result. The search for the meaning of "1 new failures" also yielded a potentially relevant result. The search for ASM Health Checker failure disk group status yielded a potentially relevant result. The search for V$ASM_HEALTH_CHECKER view Oracle did not yield a specific view. The search for best practices and monitoring alerts yielded some relevant results. The search for documentation site:oracle.com yielded some results. I will now open the most promising links. opened links provide useful information. The techdatabasket article gives a practical example. The CSDN article provides details on checker failure detection. The FlashGrid page lists ASM disk group checks. The Oracle documentation is a reference manual. The AHF release notes mention ASM disk group status. The Cleverence article explains Oracle Health Monitor. The Veritas page mentions ASMInst agent health check monitoring. The BMC page describes ASM alert log. The Oracle PDFs provide information on viewing checker findings. I have enough information to draft an article. The user's request is to "write a long article". I will structure the article with an introduction, explanation of the health checker, common causes, step-by-step troubleshooting, and prevention tips. monitoring a production Oracle Database—especially in a Real Application Clusters (RAC) environment—alert logs can contain many different messages. Among the most important ones for an Automatic Storage Management (ASM) administrator is: "ASM Health Checker found 1 new failures updated" This requires explaining what ASM Health Checker is,
Search for the exact timestamp of the health checker failure. Often, the log entry will also include a reference to the affected disk group or an ORA‑ error code (e.g., ORA‑15042, ORA‑15130).
To prevent ASM health checker issues, follow these best practices:
