The administrator's goal is to validate a server "under load" to ensure no errors occur. This requires a stress test, not just a static health check. The nvsm run diagnostics -r burnin command is specifically designed for this purpose on NVIDIA DGX systems. The burnin recipe executes a comprehensive and sustained set of high-intensity tests on all major components, including GPUs, CPUs, memory, and networking. By pushing the hardware to its operational limits, this command can uncover latent hardware faults or stability issues that would only appear under heavy, production-like workloads.

nvidia-smi -L: This command simply lists the GPUs detected by the driver. It does not apply any load or perform any validation testing.

nvsm show healthinfo: This command provides an instantaneous, static health status of components but does not run a stress test to validate stability under load.

lspci | grep -i nvidia: This is a generic Linux command to check if the operating system sees the NVIDIA devices on the PCI bus. It does not test their functionality.

1. NVIDIA DGX OS 5 User Guide (v5.2.0), Section 4.5: nvsm run diagnostics. The documentation explicitly states this command is used to "run diagnostics on the DGX system." It details the burnin recipe as a comprehensive test suite for system validation.

2. NVIDIA DGX A100 System User Guide (DU-10226-001v5.0), Section 5.3.2: Running System Diagnostics. This section describes the nvsm run diagnostics command and its recipes, including burnin, as the standard procedure for performing stress testing and hardware validation.
