Asm Health Checker Found 1 New Failures Updated Official

When a critical disk event occurs—such as a failure to write a heartbeat to the Partner Status Table (PST)—the system initiates an emergency protocol:

Visual inspection of the disk group health can also guide you:

Which environment are you running this in? I can tailor the post if it's for a specific platform like Oracle Cloud K14194: Troubleshooting the BIG-IP ASM MySQL database

By following these steps, you can troubleshoot and resolve ASM health checker failures, ensuring the stability and performance of your Oracle database and ASM environment.

To prevent ASM health checker issues, follow these best practices:

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

After a server reboot, the underlying Linux kernel may assign different raw device major/minor paths (like /dev/dm-* ) to your LUNs. If your ASM_DISKSTRING targets raw paths instead of persistent udev or ASMLib aliases, ASM loses track of its disks. 📋 Comprehensive Troubleshooting Workflow

The ASM health checker is a continuous monitoring process that checks the health and performance of ASM instances. It collects data on various aspects of ASM operations, including: When a critical disk event occurs—such as a

Query V$ASM_DISK to find disks with a status of OFFLINE or HUNG .

The exact path might vary depending on your Oracle version and installation, but the alert/log.xml location is standard in recent Grid Infrastructure versions.

Log into your ASM instance as SYSASM to run real-time health checks and view the status of your disk groups. Check Disk Group Status

When managing Oracle Automatic Storage Management (ASM), receiving an alert stating can be alarming. This message usually appears in the ASM alert log or Oracle Enterprise Manager (OEM) and indicates that the background health check process has detected a potential issue with the disk group structural integrity or a device, which requires immediate attention to avoid downtime.

In effect, the ASM Health Checker acts as a built‑in, automated diagnostics tool that confirms whether your storage structures remain healthy without waiting for user queries to hit a corrupted block.
