To ensure this abstraction layer remains robust, Oracle introduced the ASM Health Checker (typically referenced within the asmcmd utility or via the Oracle Restart/Grid Infrastructure stack). The Health Checker runs periodic validation routines to verify the integrity and accessibility of the underlying storage components.
This alert is not merely a log entry; it is a symptom of an underlying anomaly within the storage fabric of your Oracle environment. While "1 new failure" might sound minor, in the world of ASM, a single point of failure can cascade into data unavailability if left unaddressed. asm health checker found 1 new failures
In the high-stakes environment of modern enterprise IT, few things are as reassuring as a green checkmark. System administrators and database architects rely heavily on automated monitoring tools to maintain the delicate balance of their infrastructure. Oracle Automatic Storage Management (ASM) is a cornerstone of that infrastructure, managing the storage requirements of critical databases. When the status is green, all is well. But when you encounter the specific, dreaded notification——it signals a disruption that requires immediate, calculated action. To ensure this abstraction layer remains robust, Oracle
However, for the specific "Health Checker" report, you should check the specific internal views or the asmcmd failure commands: While "1 new failure" might sound minor, in
ASMCMD> lsres This lists the resource state.

su - grid asmcmd To get the real-time status and detailed error codes, run the lsop (list operation) or health check commands. However, the most direct way to investigate reported failures is looking at the failure history.
