This isn't just another routine log entry; it signals a potential integrity issue within your ASM storage infrastructure. Understanding what this alert means, why it appears, and how to fix it is a core operational skill for any Database Administrator (DBA).
Ensure your disk groups use appropriate redundancy (External, Normal, or High). Under normal redundancy, ensure no single failure group contains all copies of your critical data. asm health checker found 1 new failures updated
Look for a run that completed with STATUS = 'COMPLETED' but that produced findings. The check_name column may indicate DB Structure Integrity Check or ASM Structure Integrity Check . This isn't just another routine log entry; it
Occasionally, a backup or restore operation (RMAN) can write corrupted blocks, or a storage array can return “stale” data. The health checker detects these blocks as persistent failures, even if the database layer is not yet reporting user‑visible errors. Under normal redundancy, ensure no single failure group
The health checker uses this data to identify potential issues, such as disk failures, performance bottlenecks, or configuration problems. When an issue is detected, the health checker updates the ASM alert log with a failure message, indicating the type and severity of the problem.
If a specific disk is permanently offline:
