Asm Health Checker Found 1 New Failures Updated !!top!!

If disks are physically present but not recognized, check pvid=yes settings or try to unmount and remount the diskgroup. Scenario C: Persistent I/O Errors If a specific disk shows consistent read/write errors:

SELECT group_number, name, state, type FROM v$asm_diskgroup; SELECT path, header_status, mode_status, state FROM v$asm_disk; Use code with caution. asm health checker found 1 new failures updated

It indicates that the ASM health checker has detected in the ASM disk group’s redundancy or usability status since the last check , and that failure record has been updated in the ASM metadata or alert log. If disks are physically present but not recognized,

SQL> SELECT name, state, offline_disks FROM v$asm_diskgroup; . SQL> SELECT name, state, offline_disks FROM v$asm_diskgroup;

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"

Automatic Storage Management (ASM) is a vital component of Oracle databases, responsible for managing storage resources and providing a layer of abstraction between the database and the underlying storage devices. The ASM health checker is a built-in tool that monitors the health and performance of ASM instances, alerting administrators to potential issues before they become critical problems.
