The response to this finding must be methodical, not panicked. The first step is triage: querying V$ASM_DISK and V$ASM_OPERATION to identify the exact nature of the failure. Is the disk marked FORCED or FAILED ? Has an offline disk exceeded DISK_REPAIR_TIME ? Often, the new failure is a “stale” disk that failed to resync after a transient outage. The solution might be as simple as an ALTER DISKGROUP ... ONLINE DISK command. Other times, the failure points to degraded hardware—a flaky SAS cable, a failing SSD, or a misconfigured multipath. In these cases, the DBA shifts from technician to detective, correlating the ASM alert with OS logs ( dmesg , syslog ) and storage array warnings. The one failure demands a root cause analysis before it metastasizes into a cascade. Please acknowledge this alert in the monitoring dashboard
