Asm Health Checker Found 1 New Failures Updated →

Run crsctl stat res -t to check if disk group resources are in a STABLE or INTERMEDIATE state.

The ASM instance triggers a "dirty detach" from the lock domain, temporarily freezing portions of the Global Resource Directory (GRD) to isolate the damaged disk group while keeping unaffected groups online. Technical Context: Log Snippet Analysis

The Oracle Automatic Storage Management (ASM) alert log string indicates that the Oracle Automatic Diagnostic Repository (ADR) Health Monitor has detected a critical error within your storage architecture. This warning is triggered by underlying hardware faults, unexpected disk group dismounts, or logical corruption within ASM metadata. Missing this message or failing to fix it quickly can cause database downtime, performance bottlenecks, or total loss of data availability across a cluster. Technical Architecture of the ASM Health Checker asm health checker found 1 new failures updated

The "1 new failures updated" message does not provide detailed information about the specific issue. However, it serves as a warning that a problem exists and needs to be investigated.

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.

Ensure no physical disks are in a "Predictive Failure" or "Unconfigured-Bad" state via your storage management console. Perform Repair: If corruption is confirmed, use the CHECK ALL REPAIR command mentioned above. specific SQL queries Run crsctl stat res -t to check if

Several factors can lead to this alert, including:
