Troubleshooting "ASM Health Checker Found 1 New Failures" in Oracle Grid Infrastructure

The health checker had already updated the status, signaling the ASM instance to prepare for a "drop and rebalance". The Turning Point If a disk is offline, check the operating system messages (e

The Oracle Automatic Storage Management (ASM) Health Checker periodically polls the storage environment's overall health. Below are the most common scenarios that trigger this alert:

Even with healthy physical disks, logical corruption can affect the ASM file directory or the allocation tables. When a health checker inspects the Dictionary Integrity or the ASM Structure, it may flag a metadata object (like a file template or a disk group attribute) as inconsistent.
