The alert " ASM Health Checker found 1 new failures " is a critical notification typically found in Oracle Automatic Storage Management (ASM) alert logs. It indicates that the GMON (Group Monitor)

A single "1 new failure" is rarely a crisis, but escalate if:

Beyond the technical remediation, the message “found 1 new failure” is a powerful lesson in monitoring philosophy. It underscores the value of proactive over reactive management. A system that never reports failures is either imaginary or poorly monitored. Failures are inevitable in distributed systems. The question is not if a component will fail, but when and how prepared you are. A health checker that reliably reports a single new failure empowers the operations team to perform a planned, low-impact replacement on a Tuesday afternoon, rather than an emergency, middle-of-the-night recovery following a double failure. It transforms a potential disaster into a routine maintenance ticket. The alert " ASM Health Checker found 1

The failure involves voting disks, OCR (Oracle Cluster Registry), or the loss of disk redundancy. This can cause immediate node eviction.

When managing mission-critical enterprise environments leveraging Oracle Automatic Storage Management (ASM) , few logs are as concerning to a Database Administrator (DBA) as the Oracle ASM Alert Log. Seeing the entry indicates an immediate underlying system issue.

If ignored, this error can lead to a cascading failure of the Oracle Grid Infrastructure (CRS) stack, resulting in database crashes and potential data corruption. Root Causes of the Failure
