The most common cause is an inconsistency in the ASM metadata. This can happen due to an unexpected power loss, a bug in the storage firmware, or "lost writes." Run an internal ASM check. ALTER DISKGROUP CHECK ALL; Use code with caution. B. Offline Disks or Path Issues
The alert is a call to action to check your storage integrity. By using ADRCI to drill down into the specific failure ID, you can move from a vague warning to a concrete resolution plan. asm health checker found 1 new failures
Regularly monitor your v$asm_operation view. If you see long-running "REBAL" (rebalance) operations following a failure, ensure your ASM_POWER_LIMIT is set high enough to complete the recovery quickly without impacting database I/O. The most common cause is an inconsistency in
