2 Overview This guide provides information for the open networking (ON) diagnostic (DIAG) operating system (OS). This system uses the power-on self-test (POST) diagnostic tool that automatically runs during the system power-on at the BIOS level. This tool tests for catastrophic hardware failures that prevent booting the system. The error code is saved in CMOS for the next boot. There is no physical alarm indication. When the diagnostic tools finish, your system displays pass or fail test results. If all the tests pass, the diagnostic tools close. If a test fails, each diagnostic tool offers a different result. NOTE: The troubleshooting package includes a README file that lists the tools version and the overall troubleshooting package version. For more information, see this README file. ONIE expansion To view all the ONIE commands available, from the ONIE prompt, enter onie- and press the key twice.

POST POST diagnostics verify the system DRAM, DIMM, SPD, memory, RTC/NVRAM, and PCI devices. Test configuration parameters and test results are saved in NVRAM. Capture support data from ONIE 1. Capture support data to the screen. ONIE:/ # dmesg 2. Capture support data to the onie-support.tar.bz2 gzip file. ONIE-support creates the support file. To store the file, enter the location; for example, ONIE:/# onie-support/tmp. ONIE:/ # onie-support The ONIE support file includes the following: ● kernel_cmdline ● runtime-export-env ● runtime-process ● runtime-set-env 6 Overview
