2 ONIE diagnostics This chapter describes system diagnostics and troubleshooting. After running the diagnostic tools, your system displays pass or fail test results. If all tests pass, the diagnostic tools exit normally. 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.
System information To view your S4810-ON or N1108EP-ON system information; for example, the model, part number, serial number, and service tag, follow these steps. 1 Reboot your system and enter U-Boot mode. 2 Enter the sys_eeprom command.
EDA, Quick Test Mode Quick Test mode runs basic device access tests for the system hardware to verify that the device is active and responding. In Quick Test mode, the EDA tool quickly tests if the hardware components are accessible. It confirms that the components respond to read access and in some cases, simple write access. Tests are read-only and non-destructive (except the memtool command, which does allow read/write operations).
• Lists the current default entry. This is the default. Restoring to Factory Defaults If you need to restore the S4810-ON or N1108EP-ON factory defaults, reboot the system to ONIE Rescue using the run onie-rescue or run onie-diag commands. If it is not possible to do this with the operating system you installed, reboot the system and hit any key to stop autoboot. CAUTION: Restoring factory defaults erases any installed operating system and requires a long time to erase storage.
3 Upgrade the DIAG Installer. Again, boot to ONIE Rescue mode and install onie diag installer. NOTE: The command onie-nos-install, shown in bold, is not available in S4810-ON ONIE version 1.0.0.1; instead use the install_url ONIE:/bin # install_url command. ONIE:/ # onie-nos-install tftp://xx.xx.xx.xx/ON-DIAG//JUL-08-2014/diag-installerpowerpc-dell__on_p2020-r0.bin Stopping: discover... done. Info: Fetching tftp://xx.xx.xx.
Problem Description and Solution The pltool command ran, reports a failure, and refers to a “mismatch”. What does that mean? • The system is not allowing OS installation. Run the following command: ONIE#onie-boot-mode -o rescue The pltool command compares the firmware versions of the device(s) to the expected latest revision. This message indicates that the firmware is not the most current. Contact your Dell EMC support representative. then follow the normal installation instructions.

pcitool The PCI tool (pcitool) allows testing of the PCI devices. In EDA Quick Test mode, pcitool completes a simple check on the PCI bus. The tool scans the PCI bus for all drivers and functions and writes the configuration registers to the configuration file. Example of the pcitool Output Syntax: .

EDA Quick Test mode only completes simple access (read) tests.
Parameter Description Descriptive Device: The descriptive device (for example, SPD in the case of a dimm), is described in one comma-separated field of four parameters: address, type, start, and bytes. Device Path: The path to the device driver (for example, /dev/i2c-0 for a PD on the i2c bus 0). Address of Memory Description device (SPD): Describes the memory organization (for example, dimm memory which has an SPD device) and the address of the device.
pltool The programmable logic tool (pltool) verifies access to the complex programmable logic devices (CPLD) and field programmable gate array (FPGA) and verifies versions. The pltool generates its configuration file based on the platform database. The configuration file is generated with a specific version of devices in order to detect manufacturing misleads. The database holds all the versions and is updated when new versions are released. The configuration file displays in tree format.
R-Row Parameter Description RO — Read only RW — Read/Write RC — Clear on Read WO — Write only Default Value The default value of this register. Testable 1 — The register can be tested against the default value. 0 — The register is not testable. Version The version of the register. There can be multiple definitions of a register based on the version.

test [[all] | power supply] := test using the default config file read := read the register on the Power Supply write := write the value into the Power Supply Register fantool The fan tool (fantool) reports information about fan availability and fan speed. fantool also allows control of the fan speeds. NOTE: If you are missing a fan, the fantool test reports a failure. Example of the fantool Output Syntax: .

3 Dell EMC diagnostics The following describes the Dell EMC diagnostics. These instructions apply to systems for which the ONIE diagnostics are not available. ONIE expansion To view all the ONIE commands available, from the ONIE prompt, enter onie- and click twice.
CAUTION: Restoring factory defaults erases any installed operating system and requires a long time to erase storage. ONIE Rescue bypasses the installed operating system and boots the system into ONIE until you reboot the system. After ONIE Rescue completes, the system resets and boots to the ONIE console. 1 Restore the S6000–ON factory defaults from Grub using the ONIE: Rescue command. Use the up and down arrow keys to select which entry is highlighted.
