Dell DIAG-OS tools
This section describes how to use the Dell 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 that 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 I/O modules are down. Power on the I/O modules or the
Opticstool and
NPUtool reports failures. For information about how to power on the I/O modules, see the
Dell PowerSwitch Installation Guide for your system at
Dell Support.
