Asm Health Checker Found 1 New Failures Updated Work

The is an internal mechanism, part of the ASM Instance , that continuously monitors the integrity of the disk groups, disk headers, and metadata structures. It acts as a preventative tool, alerting administrators to issues before they become full-blown outages, such as data corruption or disk group dismounting.

WARNING: ASM Health Checker found 1 new failures updated Failure details: Disk group: DATA Disk: DATA_0003 (path: /dev/mapper/data_disk3) Failure type: OFFLINE Timestamp: 2025-01-15T14:23:10

After dropping the failed disk, the disk group will rebalance automatically. Monitor the rebalance progress via V$ASM_OPERATION .

The ASM Health Checker constantly monitors background storage components. When it logs an error update, it is usually triggered by one of the following scenarios: asm health checker found 1 new failures updated

SQL> ALTER DISKGROUP <disk group name> CHECK ALL REPAIR;

The Health Monitor stores detailed information about its checks in several database views. The primary ones are:

However, the existence of the alert raises a philosophical question about the nature of modern system administration: the reliance on automation. The ASM Health Checker is an automated agent. It runs silently in the background, parsing logs and checking parameters. When it outputs this alert, it is effectively handing off responsibility. The system has detected a fault that it cannot resolve on its own. This moment defines the role of the modern DBA—not as a mere operator who restarts services, but as a diagnostician who must interpret the automated findings. The is an internal mechanism, part of the

If you've received a notification that the "ASM health checker found 1 new failures updated," it's essential to understand what this message means and take prompt action to resolve the issue. In this article, we'll delve into the details of ASM health checking, explore the possible causes of this error, and provide step-by-step guidance on how to troubleshoot and fix the problem.

. This will automatically compare your system state against known bugs and best practices to pinpoint the exact failure. Common Root Causes

Oracle Automatic Storage Management (ASM) is a volume manager and file system designed specifically for Oracle database files. It provides a direct path to raw storage, eliminating the need for traditional file systems and simplifying storage management tasks. ASM distributes database files across all available storage devices, providing automatic load balancing and performance optimization. Monitor the rebalance progress via V$ASM_OPERATION

. This is often triggered when a monitored resource crosses a predefined threshold or a critical daemon stops responding. Immediate Review Checklist To review and resolve this failure, follow these steps: Identify the Failure Source : Navigate to Security > Reporting > Settings > ASM Alerts

While you cannot eliminate every hardware failure, you can greatly reduce the frequency of health checker alerts by following best practices:

The Health Monitor is particularly valuable for ASM because it can catch corruption in the metadata of a disk group before that corruption leads to a more catastrophic event, such as a disk group being automatically dismounted. The goal of the health checker is to provide early warnings, allowing DBAs to intervene before issues impact database operations.
