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, refer to this README file.

Capturing Support Data from ONIE To capture support data from ONIE, use the following commands. 1 Capture support data to the screen. ONIE:/ # dmesg 2 Capture support data to the onie-support.tar.bz2 gzip file. ONIE:/ # onie-support The ONIE support file includes the following: • kernel_cmdline • runtime-export-env • runtime-process • runtime-set-env • log/messages • log/onie.

ONIE Rescue bypasses the installed operating system and boots the system into ONIE until you reboot the system. 2 Press ENTER to activate the console. Example of the Optional ONIE-uninstaller Command After ONIE Rescue completes, the system resets and boots to the ONIE console. NOTE: Only use the optional onie-uninstaller command if you want to remove all the network operating software on your system except for ONIE. This command removes any installed network operating system.

Problem Description and Solution The Fantool reports a failure, but the fans seem to be working correctly. Troubleshooting tools This section describes the diagnostic tools that provide debug and hardware tests. NOTE: The following ONIE diagnostic tools do not apply to the S4048–ON and S3048–ON systems. To use the troubleshooting tools manually, you must be at the ONIE prompt and navigate to /mnt/diag/. If you are not already at the ONIE prompt, reboot your system to Rescue mode.

The memory configuration file consists of lines that describe a region of memory and the tests performed on that memory region. Therefore, you can have multiple entries for a region of memory. All parameters are separated by a : character. The following describes the configuration file parameters. Parameter Description Region Name: The region name referred to in all output. Start Address: The starting address for the region of memory in hexadecimal format (without the preceding 0x).

C-Row Parameter Description C The row identifier. Type CPLD, FPGA, or TPM. Address The address of the device. For CPLD on an I2C bus, this is an 8–bit address. For PCI, this is the bus:dev:function in a packed 32–bit word, 8–bits each. For memory, this is the address. LPC is unknown. Name The text name for the device. Interface i2c, pci, mem, io, or lpc. Bus For devices on multiple busses, this indicates the bus number (for example, 0 for i2c indicates /dev/i2c-0.
PAGE 18
B-Row Parameter Description Bit Number(s) This can be either a single bit number or a range starting with the highest bit number (for example, 7 or 7:3). Name The name of the bit. Access The access type of the bit; the same as the register definition. Default Value The default value of the bits. The following describes the I-row configuration file tree output. I-Row Parameter Description I The identifier row descriptor. Value The value of the collection of bits.

In the fantool configuration output, the first six rows describe the six fans in your system and the devices that control the fans. The second portion lists the speeds for the fans: low, medium, high, and default. The first portion of the output lists the fan IDs, name, the device that controls the fan, the fan address on the I2C bus, and the instance of the fan control within the chip. Also included is a description of which fan tray the fan is located in.
