Asm Health Checker Found 1 New Failures Updated Official

If disks are physically present but not recognized, check pvid=yes settings or try to unmount and remount the diskgroup. Scenario C: Persistent I/O Errors If a specific disk shows consistent read/write errors:

: Use the ADR Command Interpreter (ADRCI) to view the specific "incident" or "problem" that was logged. Command: adrci> show problem or adrci> show incident

# Locate your ASM Alert log using the ADRCI tool adrci> show alert -p "message_text like '%ASM Health Checker%'" Use code with caution. 2. Verify Your Current Disk Group Status

Look for errors like ORA-15080 (synchronous I/O fail), ORA-15195 (disk group corruption), or messages referencing ASM health check failure . 1.2 Identify the Failing Component asm health checker found 1 new failures updated

Upon receiving this message, administrators should:

The disk group is normal; the issue might be confined to a single disk.

If a disk is OFFLINE or MISSING , verify if the OS can still see the device path. Use multipath -ll or lsblk on Linux to check device paths. If the device is gone, it is a storage hardware issue. 5. Repair or Drop the Affected Disk If disks are physically present but not recognized,

This article provides an in‑depth breakdown of the ASM Health Checker, the meaning of “found 1 new failures updated,” and a clear, step‑by‑step guide to diagnosing and resolving the underlying problem.

Once you have identified the root cause, apply the appropriate repair strategy.

Proactive monitoring—via scheduled health checks, OEM metric alerts, and third‑party tools—ensures that you catch these failures early, often before they impact database availability. In the event of a genuine corruption that cannot be repaired, a robust backup and recovery strategy (including RMAN block recovery) will be your ultimate safeguard. If a disk is OFFLINE or MISSING ,

Ensure your disk groups have adequate redundancy (Normal or High) to survive a failure.

Log into your ASM instance via SQL*Plus ( sqlplus / as sysasm ) and run the following to see the status of your disks:

asmcmd health check

A specific check has identified an issue (e.g., failed block, metadata error, or missing disk) [Per 2.2.4].

If the CHECK ALL REPAIR command doesn't resolve the issue or if you need more details about the failure, you can delve deeper using the Health Monitor framework.
