Troubleshooting Introduction to Troubleshooting Introduction to Troubleshooting This chapter provides information about isolating a failing/failed component in a Model 743 board computer through the use of diagnostic tests and trouble shooting techniques. A failed component is traced to the level of the Field Replaceable Unit(FRU) and the FRU is replaced to correct a problem. To troubleshoot a 743 you must be familiar with the HP-UX operating system and be able to start and stop processes.
Troubleshooting Introduction to Troubleshooting ISL Environment ISL provides the means to load the operating system. ISL also provides an offline platform to execute diagnostic and utility programs contained in the LIF volume on the boot device when the operating system is not loaded. The ISL program is the first program loaded into main memory from an external media (LAN, disk, or tape) and launched by the initial program loader (IPL) routine from the Boot Administration environment.
Troubleshooting Boot ROM Selftests Boot ROM Selftests Selftests are called by a bootstrap program resident in the Boot ROM. The Selftests initialize and test the board computer hardware needed to find and boot an operating system. I/O portions for the console and boot path are tested by the I/O Dependent Code (IODC) for each I/O function. Selftest runs from PDC I/O address space except for some portions of the cache test, which downloads itself to memory.
Troubleshooting Boot ROM Selftests Hardware Initialization Support Some hardware, such as video circuit initialization and floating RAM positioning, which can not wait for a system to be booted, must be initialized at power-up as soon as possible to prevent improper operation. Go/No-Go Selftest Support The primary objective is to tell the user that the board computer can boot the operating system. This consists of indicating which devices are present and reporting all detectable failures.
Troubleshooting Boot ROM Selftests Early Selftest The Early Selftest performs initialization and Selftest functions which do not require memory. It operates on the: CPU Cache memory Memory interface I/O interface Read/Write Memory Test The read/write memory test configures and tests the memory sub-system using both writes and reads. Read-Only Memory Test The read-only memory test configures and tests the memory sub-system using reads only.
Troubleshooting Boot ROM Selftests The extended Selftest tests these devices: Time of day clock (RTC) The three timers RS-232 ports A & B SCSI LAN Graphics, if installed HP-HIL HP-IB VMEbus HP Parallel 4-7
Troubleshooting Firmware Selftest Failures Firmware Selftest Failures Two methods are used by the firmware to provide diagnostic information: the LEDs on the board computer’s front panel and ASCII encoded chassis codes which are output through the RS-232 (A) port. Interpreting the Front Panel LEDs The Model 743 provides two LEDs, located to the left and right of the reset switch, as shown in Figure 4-1. The red LED is labeled SYSFAIL and the green LED is labeled POWER.
Troubleshooting Firmware Selftest Failures Table 4-1 provides information on interpreting the system status from the LEDs. Table 4-1 LED Indicators SYSFAIL (Red) POWER (Green) Off Off No Power Check for board seating in chassis. On 2Hz Flash Normal Power-on/ selftest If the system never proceeds past this point, either the console path is not set or there is a critical CPU failure.
Troubleshooting Boot Options Boot Options If the usual boot device (typically a disk) is not responding as it should, you must attempt to boot from the disk (or another boot device) by selecting it manually. You may also want to access the ISL or Interactive Testing capabilities of the system. To access boot options, follow these steps: 1 Power off your board computer for a few seconds. 2 Turn the power back on. The system displays the following: PDC - Processor Dependent Code - Version 300.
Troubleshooting Boot Options 4 From the Main Menu, enter the following to select Boot From a Device: 1 Enter When you invoke the Boot From a Device menu item, the system displays a list of boot device categories. Which of these categories can actually be booted from depends on the system configuration: ==== BOOT DEVICE SELECT ====================== PRIMARY PATH is now [ SCSI.6.0 ] ALTERNATE PATH is now [ SCSI.5.
Troubleshooting Boot Options Scanning for Boot devices. Please wait... ==== BOOT FROM DEVICE ======================== Key Boot Device --- ----------------------------------------1 SCSI.6.0 QUANTUM FIREBALL1050S 2 SCSI.5.0 QUANTUM FIREBALL1050S 3 LAN.15.20.93.16 INSTALL 15.20.93.16 4 LAN.15.20.88.47 INSTALL 15.20.88.47 5 LAN.15.20.88.100 INSTALL 15.20.88.100 6 LAN.15.20.88.96 INSTALL 15.20.88.96 7 LAN.15.20.92.249 INSTALL fibula ... .........................................
Troubleshooting Interactive Testing Menu Interactive Testing Menu Once in the Boot Console Handler Mode, at the Main Menu, select Interactive Tests. This menu, shown below, allows a user to run selected tests and allows access to the debugger environment. Table 4-2 lists the types of test you can run from the Interactive Test menu. ==== INTERACTIVE TESTING ===================== Key Operation --- ----------------------------------------1 CPU S.S.
Troubleshooting Running ODE-Based Diagnostics Running ODE-Based Diagnostics The Offline Diagnostic Environment (ODE) consists of diagnostic modules for testing and verifying system operation. ODE provides all the necessary functions for the user to load specified tests and interact with those tests. ODE is an ISL utility. To boot ODE: 1 Invoke the ISL environment from the system disk. 2 Type ode after the ISL> prompt to invoke ODE from the LIF directory on the system disk. The prompt changes to ODE>.
Troubleshooting Determining the Faulty RAM Card Determining the Faulty RAM Card If a memory failure is detected during memtest execution, the failing memory card is indicated. The following lists shows the location of the RAM stacks: • RAM stack 1 is located behind the two PS/2 connectors on the board computer’s right side. • RAM stack 2 is on the other side behind the LEDs and Audio port. • The low-number slot position is next to the system board.
Troubleshooting Running System Verification Tests Running System Verification Tests HP-UX uses an online diagnostics product called the Support Tools Manager that allows system operation verification. HP-RT does not support online diagnostics. Three interfaces are available with the Support Tools Manager: a command line interface (accessed through the cstm command), a menu-driven interface (accessed through the mstm command), and the graphical user interface (accessed through the xstm command).
Troubleshooting Running System Verification Tests To access the Support Tools Manager, you must be logged in as “root” or “superuser”, and perform the following steps: 1 In a terminal window, type the following at the # prompt to invoke the command line interface: # cstm 2 The following message appears: Support Tool Manager Version A.01.
Troubleshooting Dealing with HPMC (Uncorrectable Error) Dealing with HPMC (Uncorrectable Error) The power-on sequence follows this path: Power-on -> Selftest -> Console Path -> Boot Admin Mode -> Boot Path -> ISL Mode -> Operating System Mode When the hardware detects an unrecoverable (HPMC) error in the Operating System environment, an error message, referred to as a Kernel Tombstone is displayed on the monitor.
Troubleshooting Dealing with HPMC (Uncorrectable Error) To identify the failed FRU(s) after an HPMC, follow these steps: 1 Examine the “Other Processor Data” words returned from the PIM command to display the latest error information from the last TOC, LPMC, or HPMC interruption detected. 2 Compare the values from the PIM command with those shown in Table 4-4 and take the appropriate action.
Troubleshooting Dealing with HPMC (Uncorrectable Error) Table 4-4 PIM Action Table Check Type Word Cache Check Word Bus Check Word System Responder Word Action 0x20000000 N/A 0x00310007 0xF4000000 0xF5FFFFFF Replace Graphics in GSC Slot 2, if present, otherwise check VME cards, and/or replace CPU board. 0x20000000 N/A 0x00310007 0xF6000000 0xF7FFFFFF Check VME system configuration and/ or replace CPU board.

Troubleshooting Dealing with HPMC (Uncorrectable Error) HPMC Caused by a Data Cache Parity Error For example, an HPMC interruption is forced when a data cache parity error is detected during a load instruction to the memory address space or during a data cache flush operation. Table 4-5 shows an example of the HPMC error information retrieved from Stable Storage by the PIM command from the Interactive Testing Debug Environment.
Troubleshooting Dealing with HPMC (Uncorrectable Error) HPMC Caused by a Multi-Bit Memory Parity Error An HPMC interruption is forced when a multi-bit memory parity error is detected during a “DMA read” operation or fetching an I/D cache line (32 bytes). Table 4-6 shows an example of the HPMC error information retrieved from Stable Storage by the PIM command from the Interactive Testing Debug Environment.
Troubleshooting Dealing with HPMC (Uncorrectable Error) Determining the Faulty Memory Card Memory is configured in a contiguous fashion starting at a base hexadecimal address of 0x00000000 to a maximum of 0x0FFFFFFF (256MB). Memory is installed on the Model 743 in two stacks of up to four memory cards of 8MB, 16MB, 32MB, or 64MB capacity.
