To help me give you more specific troubleshooting steps, could you tell me: What is the or code?
-- Check detailed status of all disks in all disk groups SELECT group_number, disk_number, name, path, state, mode_status, header_status, total_mb, free_mb FROM v$asm_disk;
: In diskgroups with redundancy (Normal or High), if too many disks or a required "voting" disk (PST) become unavailable, the group cannot maintain a read quorum and will fail. asm health checker found 1 new failures
The hum of the server room was usually a comforting white noise for Leo, the lead DevOps engineer. But at 3:00 AM, that hum sounded more like a low-pitched warning.
If ignored, this error can lead to a cascading failure of the Oracle Grid Infrastructure (CRS) stack, resulting in database crashes and potential data corruption. Root Causes of the Failure To help me give you more specific troubleshooting
-- 2. From the output, note the NAME of the relevant health check run (e.g., 'HM_RUN_123') -- 3. Generate the detailed report for that specific run SET LONG 100000 LONGCHUNKSIZE 1000 LINESIZE 512 SELECT DBMS_HM.GET_RUN_REPORT('HM_RUN_123') FROM DUAL;

After fixing the issue, the ASM health checker will automatically re-evaluate within 1 hour (by default). To force an immediate recheck:
(Invoking related search terms tool for People/Places/Shopping/etc. is not needed here.) But at 3:00 AM, that hum sounded more
In cloud or virtualized infrastructure, an underlying network flap can interrupt multipath software (e.g., Device Mapper Multipath). If all redundant paths to a LUN drop simultaneously, ASM interprets this block-level device vanishing act as a device failure. ASM-ALERTLOG-Output-Failure-CELLI03-and-CELL01
