This specific notification usually indicates that an automated tool—like the Oracle Autonomous Health Framework (AHF) F5 BIG-IP ASM —has detected a change in your system's health status.

Several factors can lead to this alert, including:

By systematically reviewing the ASM alert log, running manual disk group checks ( ALTER DISKGROUP ... CHECK ), querying the Health Monitor history ( V$HM_RUN and DBMS_HM.GET_RUN_REPORT ), and applying the appropriate repair (from automatic REPAIR to disk replacement), you can resolve the issue and restore your ASM infrastructure to a fully healthy state. asm health checker found 1 new failures updated

If you need help decoding specific failure codes from the ASM alert log, paste the relevant lines (sanitized) for further assistance.

The ASM Health Checker runs continuously within the background processes of an ASM instance (specifically managed by components like the and Global Enqueue Service (LMON) ).

Replace 'HM_RUN_NAME' with the specific run name from the V$HM_RUN table.

Ultimately, the alert "ASM Health Checker found 1 new failures updated" serves as a testament to the resilience engineered into modern database systems. It represents a tiered defense mechanism where software monitors hardware, and automation supports human judgment. While the alert may induce a spike of adrenaline for the on-call engineer, it is a preferable alternative to the silence of an undetected failure. In the world of data storage, visibility is survival, and this alert ensures that no failure remains hidden in the dark. Immediate investigation is required to determine if the

The operating system has lost connectivity to the device, or multipathing software (e.g., PowerPath, Device Mapper) is misconfigured.
