Verify physical hardware or multipathing configurations to ensure the device path (e.g., /dev/sdg1 ) is still visible to the OS.
Rarely, the message appears without any actual hardware or storage issue. This can happen due to: asm health checker found 1 new failures updated
And review the ASM alert log for any earlier signs of deterioration. The disk group has dropped offline
The disk group has dropped offline. This indicates a loss of disk quorum. 3. Check for Ongoing Rebalance Operations Check for Ongoing Rebalance Operations Depending on where
Depending on where you want to share this (e.g., Slack for your team, or a technical status update), here are a few options: Option 1: Internal Team Alert (Slack/Teams) ASM Alert: New Failure Detected The ASM Health Checker has just reported 1 new failure Next Steps: Checking the and running tfactl diagcollect to grab the latest logs for investigation.
The ASM Health Checker is an internal diagnostic tool embedded within Oracle ASM (introduced in Oracle 11g Release 2 and enhanced in 12c, 18c, 19c, and 21c). Its primary function is to periodically validate the integrity, accessibility, and configuration of ASM disk groups and their underlying disks.
Ultimately, the alert "ASM Health Checker found 1 new failures updated" serves as a testament to the resilience engineered into modern database systems. It represents a tiered defense mechanism where software monitors hardware, and automation supports human judgment. While the alert may induce a spike of adrenaline for the on-call engineer, it is a preferable alternative to the silence of an undetected failure. In the world of data storage, visibility is survival, and this alert ensures that no failure remains hidden in the dark.
