The correct resolution depends on the findings from the previous steps.
Fix: Clear out old UCS files or decrease the log storage period in your logging profile. Use df -h in the CLI to verify space. 3. ASM Policy Synchronization

Once you've identified the root cause of the failure, take corrective actions to resolve the issue: asm health checker found 1 new failures
SELECT group_number, disk_number, mode_status, header_status, name FROM v$asm_disk; Use code with caution. Look for disks with a MODE_STATUS of OFFLINE .
This command provides a unique and a description of the problem.
Your first diagnostic step is to view the Grid Infrastructure alert log. This log is typically located under the Automatic Diagnostic Repository (ADR) home.
Recently, you may have encountered an alert or message indicating that the "ASM health checker found 1 new failure." This message can be concerning, especially if you're not familiar with what it means or how to resolve it. In this article, we'll explore what this message means, the possible causes, and step-by-step instructions on how to resolve the issue. The correct resolution depends on the findings from
To fix the failure, you first have to identify it. You can do this via the Command Line Interface (CLI) using ADRCI . Step A: Access ADRCI Log in to your grid infrastructure server and run: adrci Use code with caution. Step B: Set the Home Path
Fix: Run the repair utility: /usr/share/ts/bin/add_del_internal add repair_db 1 (Note: This may require a restart of the ASM services). 2. Partition Disk Usage
The failure relates to performance bottlenecks, slow I/O response times, or asymmetrical disk sizes within a disk group.

The DBMS_HM.GET_RUN_REPORT function returns a detailed report, including the specific Finding Name (e.g., "System datafile is old"), its Type (e.g., FAILURE), Priority (e.g., CRITICAL or HIGH), and a descriptive message. This report is invaluable for understanding the exact nature of the problem.
Execute the CHECK command: ALTER DISKGROUP CHECK ALL; Note: This checks for consistency but does not fix errors. If errors are found, you may need to involve Oracle Support. Scenario C: Space Pressure
Alternatively, use the CLI to check the logs: grep "health_checker" /var/log/asm Step 2: Common Failure Scenarios and Fixes 1. Database Table Crashes
