ASM background process is capturing diagnostic data after a failure.
ASMCMD [+] > chkdg --repair data
Although rare, ASM metadata (e.g., the File Directory, Alias Directory, or PST (Partnership and Status Table)) can become corrupted due to hardware errors or improper shutdowns. The health checker’s metadata validation routines will detect inconsistencies.
The alert message is just the "headline." You need to find the specific error code (like ORA-15032 or ORA-15078).
Oracle Enterprise Manager exposes several ASM metrics that correlate with health checker failures:
If a specific disk is permanently offline:
Remember: Ignoring the alert can lead to a cascade of failures, especially in lower redundancy configurations. With the diagnostic steps and remediation strategies provided in this guide, you can confidently resolve the alert and restore your ASM environment to full health.
