The operating system detected a firmware error on the hardware of the host, triggering the alert.
Hardware fault: the host {.labels.hostname} encountered a firmware error, and the error code is { .labels.fault_code }. The error log recorded in the OS is:{ .labels.message }
The hardware corresponding to the faulty firmware may be in an abnormal working state, posing potential risks.
Possible causes include:
The firmware code itself has defects.
The firmware detects a hardware anomaly and reports it to the operating system.
If the hardware corresponding to the faulty firmware is a redundant device on the node (such as a physical disk or NIC), you can temporarily isolate the device to avoid impact on services:
Physical disk: Unmount the physical disk in AOC.
NIC: If multiple NICs are configured in bonding mode, log in to the host and disable the network port of the faulty NIC. Traffic will automatically switch to healthy links.
If the hardware corresponding to the faulty firmware is the only device of its kind on the node and cannot be isolated, it is recommended to put the host into maintenance mode and migrate virtual machines to other healthy nodes. After the issue is resolved, exit maintenance mode and migrate the virtual machines back as needed.
To completely resolve the hardware issue, contact the hardware vendor to confirm whether it is a known firmware version issue or a hardware failure, and upgrade the firmware or replace the hardware as recommended.
