Asm Health Checker Found 1 New: Failures Updated [patched]

The ASM alert log contains a chronological log of messages and errors. Scan for the timestamp of the "ASM Health Checker found 1 new failures" message to see what other errors are logged around the same time. This can provide critical clues about the specific problem.

The "ASM Health Checker found 1 new failures" message is a serious indicator that your Oracle ASM disk group integrity is compromised. To effectively handle this situation:

Health checks detect file corruptions, physical and logical block corruptions, undo and redo inconsistencies, and data dictionary corruption. When any of these targeted validations fail, the Health Checker logs an entry into the ASM alert log ( alert_+ASM.log ) and, in many monitoring environments, triggers an Enterprise Manager (OEM) metric alert. asm health checker found 1 new failures updated

The health checker uses this data to identify potential issues, such as disk failures, performance bottlenecks, or configuration problems. When an issue is detected, the health checker updates the ASM alert log with a failure message, indicating the type and severity of the problem.

In rare cases, the disk group metadata is temporarily inconsistent but not corrupt. Unmounting and remounting the group can force a metadata refresh: The ASM alert log contains a chronological log

Before making any changes, retrieve the trace file that corresponds to the background error. Look for lines right above the alert in your ASM alert log to identify the specific RBAL or GMON background trace file.

when ASM's internal monitoring identifies a change in the status or integrity of a disk group. Incident Summary ASM Health Checker 1 New Failure Found The "ASM Health Checker found 1 new failures"

If the underlying cause is a physical disk failure, you will need to identify and replace the failing disk. Use the following query to view the health of all disks in a disk group:

A physical drive, virtual block device, or storage area network (SAN) path experiences deep queue latency or drops offline. 2. Force Dismount Triggers

. This system continuously monitors Oracle Automatic Storage Management (ASM) and cluster environments for issues related to stability, configuration, and performance. Understanding the Notification

The instance logs an explicit ORA-15130 (Diskgroup being dismounted) error, followed immediately by the ASM Health Checker found 1 new failures summary event. 4. Dirty Detach Execution
