In this article, we will delve into what this error means in 2026, the common causes, and how to identify and resolve it efficiently, citing best practices from Oracle documentation . What Does This Alert Mean? asm health checker found 1 new failures updated

Disks in FORCING state (attempting recovery) or OFFLINE state are the culprits.

user wants a long article on the keyword "asm health checker found 1 new failures updated". This appears to be a message from an automated system, likely related to Oracle ASM (Automatic Storage Management). The article should be informative, covering what ASM is, the health checker, the meaning of the message, troubleshooting steps, etc. To get a good overview, I need to search for this exact phrase and for more general information about ASM health checks. I'll also look into Oracle ASM itself and its health check mechanisms. search results show several relevant pages. The top result from techdatabasket.com appears to be a blog post specifically about this message. Another result from blog.csdn.net mentions an OEM triggered alert. There are also references to Oracle documentation and other resources. To fully understand the context and provide a comprehensive article, I need to open these pages. techdatabasket blog post provides a practical example. The CSDN post explains the cause and solution. The orasos page shows a real-world example. I also see references to Oracle documentation. Now I need to write a long article. The article should cover: introduction to ASM, what the health checker is, what the message means, how to investigate, how to resolve, and best practices for prevention. I'll structure it with sections. I'll also search for more information on Oracle ASM and health checks.'ve gathered enough information to write a comprehensive article.

A physical disk or LUN has become unreachable or is experiencing intermittent latency.

If you are using External Redundancy , a single disk failure can make the entire disk group unrecoverable ("toast"). Command: adrci> show problem or adrci> show incident

SQL> SELECT group_number, disk_number, name, state, path FROM V$ASM_DISK WHERE state != 'NORMAL';

Automatic Storage Management (ASM) is Oracle’s volume manager and file system, built specifically for database files. It manages disk groups, handles storage redundancy (Normal, High, or External), and balances I/O. However, even with robust redundancy, disk corruption or metadata corruption can occasionally occur.

In one documented case, a DBA encountered this alert alongside an "invalid ASM block header" error, where a comparison of block values ( 6999 != 6743 ) indicated a mismatch in block data. This type of corruption indicates that a block within the disk group has been altered or overwritten incorrectly. The health checker is designed to detect such anomalies through routine scans, providing a critical safety net for your storage environment.
