Search for keywords like ORA- , ASM , or ERROR around the timestamp of the health checker alert. 3. ASM Instance Alert Log
Always use robust multipathing to prevent single-path failures from triggering this alert.
Run the following SQL query within the SQL*Plus environment of the affected ASM instance to identify the disk group's operational mode:
While Oracle performs default health checks, you should also schedule custom checks on a weekly or monthly basis. Use a script that runs ALTER DISKGROUP ... CHECK ALL NOREPAIR and logs the output for review.
: Use the ADRCI Command-Line Utility to view the full error stack surrounding the "1 new failures" message.
When a DBA sees "ASM Health Checker found 1 new failures updated," the response must be methodical. Panic is the enemy; the alert is a tool, not an accusation. The administrator must query the V$ASM_HEALTH view or check the alert logs to pinpoint the specific component that triggered the failure. Was it a rebalance operation that failed? Is a disk currently offline? Is there a quorum failure in a clustered environment? The alert is the starting gun for a forensic investigation.
Oracle ASM includes an automatic health check feature that constantly monitors the health of ASM diskgroups and the underlying physical disks.
The Oracle Automatic Storage Management (ASM) health checker is a critical diagnostic tool designed to automatically detect issues with diskgroup consistency, redundancy, and I/O performance. Receiving the alert "ASM Health Checker Found 1 New Failures Updated" indicates that the checker has identified a potential issue with a disk, diskgroup, or metadata.
