Several factors can lead to this alert, including:

If the health check report identifies a repairable problem—such as a minor metadata inconsistency—the safest first step is to attempt an automated repair. Use the REPAIR clause with the ALTER DISKGROUP command:

If you are an Oracle Database Administrator (DBA) managing an Oracle Real Application Clusters (RAC) environment, you have likely encountered a cryptic but critical message in your alert logs or monitoring console: asm health checker found 1 new failures updated

Check REQUIRED_MIRROR_FREE_MB . If your usable space is negative, the system may not have enough room to rebalance data and restore redundancy after this failure.

There are several possible causes for ASM health checker failures, including:

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.

Depending on where you want to share this (e.g., Slack for your team, or a technical status update), here are a few options: Option 1: Internal Team Alert (Slack/Teams) ASM Alert: New Failure Detected The ASM Health Checker has just reported 1 new failure Next Steps: Checking the and running tfactl diagcollect to grab the latest logs for investigation.

Then the health checker will flag this as a new failure.

Implement these settings to stop recurring health check failures in production.
