Look for disks with a state of FAILED , FORCING , or HUNG . An unhealthy disk is a common cause of the alert.

The Automatic Storage Management (ASM) health checker is a crucial tool in Oracle databases that monitors the health and integrity of the storage infrastructure. When the ASM health checker reports a new failure, it's essential to understand the implications and take corrective actions to prevent data loss or system downtime. In this blog post, we'll discuss what an ASM health checker failure means, how to investigate the issue, and steps to resolve it. asm health checker found 1 new failures

By understanding the causes of ASM health checker failures and taking proactive steps to prevent them, you can ensure the reliability and performance of your Oracle database storage infrastructure.

If the alert persists in Enterprise Manager or Oracle Cloud Infrastructure (OCI) console dashboards despite resolving the root cause, manually clear or acknowledge the alert tracking history to reset the baseline monitor. Best Practices for Preventing ASM Failures

: A disk may have failed, leading to a loss of redundancy or a disk group being forced to dismount.

If your secret uses a resource-based policy, ensure it does not contain a explicit Deny block that inadvertently catches the health checker's IAM role. 3. Audit AWS KMS Key Permissions

Once the underlying storage, network, or metadata anomaly is resolved, verify that the health checker returns a clean status. An unhealthy disk is a common cause of the alert

After the underlying issue is resolved (e.g., the disk is back online or the metadata is repaired), you need to "close" the failure in the ADR so the health checker stops reporting it. Inside ADRCI :

Navigate to the log group associated with your health checker (e.g., /aws/lambda/SecretsManagerHealthChecker ).

: The metadata (headers) on one or more ASM disks may be corrupted or in a "FORMER" or "PROVISIONED" status instead of "MEMBER". Voting File Issues
