offline-GPU-fault-diagnosis

To diagnose a GPU fallen off the bus, you can analyze offline server logs like iBMC, OS messages, and InfoCollect data. This process correlates hardware and software events to identify whether the root cause is physical PCIe link degradation, power fluctuation, or a driver-level software hang.

Determining if an XID error is a hardware or software issue requires multi-dimensional log correlation. By aligning NVIDIA driver XID errors with OS kernel messages and iBMC hardware events, you can validate the actual root cause and distinguish genuine hardware failures from software-induced pseudo-faults.

Yes, you can pinpoint the specific physical slot of a failed GPU from offline collected data. By analyzing InfoCollect data and OS logs, the diagnosis process identifies the exact GPU slot and BDF address to locate the physical source of hardware instability or driver faults.

Yes, multi-source log correlation helps with PCIe link instability and ECC memory faults. Aligning iBMC hardware events with OS kernel messages reconstructs the exact fault propagation chain, validating hardware versus software root causes for these specific GPU hardware and driver failures.

To analyze iBMC hardware events and OS kernel messages for a GPU driver hang, align the hardware events with OS messages and InfoCollect data. This multi-dimensional correlation validates the root cause by reconstructing the fault propagation chain across the server environment.
