Dealing with a Boot Failure If the workstation’s 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 manu- ally. To boot a device manually, follow these steps: Turn off the power to the workstation, wait a few seconds, then turn the power back on.
When the search ends, the following list of actions appears: Boot from specified device Search for bootable devices Enter Boot Administration mode Exit and continue boot sequence Help Select from menu: If no disk devices are listed, then the workstation is failing to communicate with its disks.
Set or display the Fastsize value (amount of memory initialized during boot) using the FASTSIZE command. Display a menu of commands using the HELP command or a description of any command as an option to the HELP command. Display the model number, version numbers, and jumper settings on the Sys- tem card using the INFO command.
Boot Command Notations The BOOT command supports the following three notations: Mnemonic PA–RISC I/O Path number Type help scsi or help lan for more information on the boot path parameters. Here are examples of mnemonic notation: BOOT with “no parameters” selects the primary boot path in stable Return storage.
ISL Environment The ISL environment provides the means to load the operating system (HP–UX) environment. The ISL environment also provides an offline platform to execute diag- nostic and utility programs from a boot device when HP–UX does not load. 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 during the Boot Administration environment.

To terminate search, press and hold the ESCAPE key. Device Selection Device Path Device Type ––––––––––––––––––––––––––––––––––––––––––––––––––...
ISL User Commands There are several commands available in the ISL environment that allow a user to obtain information about the boot characteristics of the system or to modify these characteristics. display – displays the boot and console paths in Stable Storage and the current setting of the ISL Boot Flags.
Type eisadiag after the prompt to invoke the EISADIAG test Return ISL> from the external media. NOTICE: eisadiag requires an EISA bus tester card (part num- ber A1421-66533) to fully test the functionality of the EISA adapter board. Without the bus tester card, eisadiag will only partially test the EISA adapter board.
Verifying the System Operation with SupportWave SupportWave contains the Support Tools Manager to verify system operation. You can access the Support Tools Manager while in a terminal window; if you are using HP–VUE as your interface, you can also access the Support Tools Manager through the sys_admin directory.
The following messages appear: Verification has started on device (CPU). Verification has started on device (FPU). Verification has started on device (0/0/0). Verification has started on device (2/0/1.0.0). Verification has started on device (2/0/1.5.0). Verification has started on device (2/0/1.6.0). Verification has started on device (2/0/2).
Dealing With HPMC (Uncorrectable Error) The power–on sequence follows this path: POWER-ON > SELFTEST > CONSOLE PATH > BOOT ADMIN MODE > BOOT PATH > ISL MODE > HP-UX MODE When the hardware detects an unrecoverable (HPMC) error in the HP-UX environ- ment, an error message, referred to as an HP-UX Kernel Tombstone is displayed on the monitor.

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 of fetching an I/D cache line (32 bytes). Table 4–7 shows an example of the HPMC error information retrieved from Stable Storage by the PIM_INFO command during the Boot Administration environment.
Determining the Faulty SIMM Pair The address given by the System Responder Address is given as if the memory is contiguous, even though empty slots are permitted. Memory boards are installed in pairs of the same memory capacity. The operating system starts mapping memory at Pair 3, if it exists.
Determine the SIMM pair that contains the System Responder Address (as shown using the PIM_INFO command) within its range. Evaluate the SIMM pairs, as follows: NOTICE: Addressing starts at Pair 3, not Pair 0. Without the actual failed bit number, the failed pair number is as close a deter- mination as possible.
HPMC Caused by a Data Cache Parity Error An HPMC interruption is forced when a data parity error is detected during a Load instruction to the memory address space or during a data cache flush operation. Table 4–9 shows an example of the HPMC error information retrieved from Stable Storage by the PIM_INFO command during the Boot Administration environment.
Troubleshooting CRX and HCRX Graphics If the workstation has one of the CRX or HCRX graphics options installed, and there is no output on the monitor, use the following procedure to troubleshoot the problem: Power off the workstation and the monitor. Make sure that all connectors and cables are fully seated and that the monitor is connected to the correct connector for the CRX or HCRX graphics option.
After you press the TOC switch, power off the workstation. Wait a few se- conds, then power it back on. If, after a few minutes, you still have nothing displayed on the monitor, the monitor is defective. Replace the monitor. Otherwise continue with Step 10. Follow the procedures described in the “Configuring the CRX or HCRX Graphics Options”...
