Dell EMC DIAG-OS tools

This section describes how to use the Dell EMC diagnostics operating system (DIAG-OS). The DIAG-OS provides a suite of tools to help

diagnose issues seen on the system, or to run a health check to ensure that the hardware is operating properly.

Diagnostic tools

The DIAG-OS uses standard Linux drivers and contains the following tools you can use to evaluate the health of your system. The tools

are packaged for both the DIAG-OS, which is a simple OS of the same kernel version, and small rootfs to support the tools and drivers.

NOTE: By default, the system’s I/O modules are down. Power up the I/O modules or the Opticstool and NPUtool reports

failures. For information about how to power up the I/O modules, see the

Dell EMC Installation Guide

for your system at
