Firmware Updates: Many health check bugs are resolved in newer Engineering Hotfixes (EHF).

After the underlying issue is resolved (e.g., the disk is back online or the metadata is repaired), you need to "close" the failure in the ADR so the health checker stops reporting it. Inside ADRCI :

This message is not a generic warning; it is a definitive notification that the Oracle Grid Infrastructure internal health engine has detected a severe failure. This typically involves physical or logical storage layer degradation. Understanding what this message means, why it occurs, and how to methodically resolve it is critical to preventing cascading multi-node cluster evictions or database downtime. Anatomy of the Error Message Here is a story of a "typical" Friday

To identify the exact cause, execute the following steps within your environment:

Once you have fixed the underlying physical or logical issue, the Health Checker should automatically update during its next run. However, if the status remains "Failed" in the views, you can manually trigger a re-run of the health check or use ADRCI to purge the alert. Summary Checklist

The log warning indicates that an Oracle Automatic Storage Management (ASM) background monitoring process has detected a critical hardware, connectivity, or configuration issue. This message frequently surfaces in the ASM alert log immediately following infrastructure complications like I/O timeouts, sector corruptions, or storage network drops. When it drops into your logs, it signals that the ASM layer has isolated a fault to protect your database cluster from split-brain scenarios or data loss.
