: If the ASM disk group hosts the Cluster Registry (OCR) or Voting Disks, a failure can cause node evictions or cluster instability. Storage Latency/I/O Timeouts
The failure can be related to various aspects of ASM, such as:
Heavy traffic causing the ASM engine to respond slowly to the health probe.
If the failure is related to "Insufficient Space," rebalance the disk group or add new disks immediately. asm health checker found 1 new failures
At first glance, a single failure might seem trivial. After all, modern ASM configurations are built on pillars of redundancy: normal redundancy, high redundancy, and robust failure groups. A single disk slowing down or a single network path intermittently dropping packets could be masked by the system’s inherent self-healing capabilities. However, the health checker is not an alarmist. It is a sentinel. The designation of “1 new failure” implies a delta from a previous state of health. Something, somewhere, has crossed a threshold from acceptable to aberrant. That one failure is the canary in the coalmine.
Monitor Memory: Keep an eye on the "Management" memory allocation. ASM is memory-intensive.
This is the standard SQL command for triggering an ASM disk group consistency check. : If the ASM disk group hosts the
Please acknowledge this alert in the monitoring dashboard. If the issue is resolved, update the ticket with the root cause analysis (RCA).
Once you have identified the name of the specific health check run from the V$HM_RUN view (e.g., 'HM_RUN_1061'), generate a detailed report to pinpoint the exact failure.
If the analysis confirms a correctable form of corruption, the most direct solution is to run the CHECK command with the REPAIR clause. At first glance, a single failure might seem trivial
A structured approach is essential. Do not panic. Follow the diagnostic pathway that matches your environment.
If you are a database administrator, this message likely originates from Oracle's Automatic Storage Management. The ASM Health Checker is an internal utility that regularly scans your ASM disk groups for:
