Asm Health Checker Found 1 New Failures Updated Exclusive

When it detects a discrepancy—such as a corrupted metadata block, a disk timeout, or an offline disk—it logs a "failure." The "Updated" status usually means the health check engine has refreshed its findings and confirmed that the issue is persistent and requires administrator intervention. Common Causes for This Alert

| Failure Type | Example | |-------------|---------| | | A disk in a disk group is offline or missing. | | Disk path error | Underlying LUN/device path inaccessible. | | Read/write errors | OS or storage reports I/O errors. | | Stale disk | Disk not synchronized with partner disks. | | Failure group issues | Entire failure group degraded. |

: Post-maintenance updates altered the ownership of /dev/oracleasm/disks or UDEV rules, blocking Grid Infrastructure access. asm health checker found 1 new failures updated

The ASM alert log contains a chronological log of messages and errors. Scan for the timestamp of the "ASM Health Checker found 1 new failures" message to see what other errors are logged around the same time. This can provide critical clues about the specific problem.

If a disk dropped due to an intermittent SAN path loss but the hardware is now stable:

Upon receiving this message, administrators should: Monitor the rebalancing process via SELECT * FROM

When ASM Health Checker detects a problem, it updates the failure status and sends notifications to administrators.

If disks are physically present but not recognized, check pvid=yes settings or try to unmount and remount the diskgroup. Scenario C: Persistent I/O Errors If a specific disk shows consistent read/write errors:

The following sequence demonstrates how this failure manifests within an active Oracle RAC or standalone Grid Infrastructure environment: | | Disk path error | Underlying LUN/device

The REPAIR clause instructs Oracle ASM to automatically fix any inconsistencies found during the check process. After running this command, the alert will be resolved, and the disk group will be consistent.

The "ASM Health Checker found 1 new failures" message is a serious indicator that your Oracle ASM disk group integrity is compromised. To effectively handle this situation:

If the health checker continues to report the same failure after attempting repairs—or if the DBMS_HM.GET_RUN_REPORT indicates a critical data dictionary corruption—you should open a Service Request with Oracle Support. Provide the full Health Monitor report, the ASM alert log snippet, and the output of V$ASM_DISKGROUP and V$ASM_DISK .

Update your UDEV rules file if permissions reset after a reboot. Reload UDEV triggers using udevadm trigger . Clear the Health Checker Alert

Because the Health Checker runs repeatedly—and because failures are tracked as persistent—the message also includes the word “updated” to confirm that the failure count has been refreshed from the latest diagnostic run.
