If a path to a physical disk is lost (due to HBA failure or cable issues), ASM might mark the disk as "OFFLINE." If the diskgroup is still mounted but missing a member, the Health Checker will flag it.
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. This message is usually triggered by the Oracle
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 :
