Asm Health Checker Found 1 New Failures Updated [TOP]

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

If a disk is offline, check the operating system messages (e.g., /var/log/messages on Linux or dmesg ). Look for SCSI errors or timeout messages. If the OS cannot see the LUN, the issue is at the hardware or SAN level, not the Oracle level.

Always ensure your critical disk groups are at least on "Normal" redundancy to allow the health checker to find and fix issues without taking the database offline.

Introduction The message "ASM health checker found 1 new failures updated" signals that a monitoring component (an ASM health checker) has detected and recorded a newly identified failure in a system. This brief notification encapsulates operational realities—detection, state change, and the need for response—and invites examination of its technical meaning, potential causes, implications, and recommended actions.
