Troubleshooting "ASM Health Checker Found 1 New Failures" Oracle Automatic Storage Management (ASM) is the backbone of storage management for Oracle Databases. When Oracle Grid Infrastructure generates an alert stating it means the internal ASM Health Checker (AMHC) framework has detected a specific vulnerability, corruption, or performance degradation within your storage tier. asm health checker found 1 new failures

After fixing the issue, the ASM health checker will automatically re-evaluate within 1 hour (by default). To force an immediate recheck: Detect and notify when the ASM (Application Security

When ASM writes this specific line to the alert log, it is almost always responding to a severe breakdown in the underlying I/O subsystem. The most common triggers include: KB88485 - My Oracle Support

Look for lines containing SQL> select * from v$asm_health_check or health_check_summary . You will see a failure line like: "Check: Disk Path Accessibility, Status: FAIL, Details: Disk DATA_0002 path /dev/mapper/asm_data2 is not readable"

When servers reboot after operating system patching or storage migrations, the asm_diskstring parameter might scan multiple physical paths pointing to the exact same logical unit number (LUN). If ASM detects duplicate headers or cannot definitively parse which path is authoritative, the Health Checker raises an exception and will refuse to mount the affected disk group. 4. Block Corruption When Oracle Grid Infrastructure generates an alert stating
