Troubleshooting

Dealing with a Boot Failure

Searching for Bootable Media

To list all devices that may contain bootable media, go to the Main Menu of the Boot Console Interface and then type the following at the prompt:

Main Menu: Enter a command or a menu > search ipl

The search may turn up more devices than there are lines on the display. If using a text terminal, you can control the progress of the search from the terminal’s keyboard by performing the following steps:

•To hold the display temporarily, press Ctrl S

•To continue the display, press Ctrl Q

•To halt the search, press Esc

These flow-control commands do not work with a bitmapped display, but such a display can show more than forty lines of text, so they are unnecessary.

To search for devices of just one type that actually contain bootable media, go to the Main Menu of the Boot Console Interface and then type the following at the prompt:

Main Menu: Enter a command > search ipl device_type

where device_type is one of the following:

•scsi is the built-in fast, Ultra2 Wide LVD (Low Voltage Differential) SCSI bus.

•lan is all connections to the built-in LAN.

•ide is the built-in CD drive.

•pcin is an optional plug-in device in PCI slot number n.

•disk is any bootable device other than LAN.

Stable Storage

Stable Storage is non-volatile memory associated with each PA-RISC processor module. Stable storage is used by the processor (CPU) to store device path information, the state of the boot flags, HPMC error information, and operating system initialization data.
