HP-UX System Administrator's Guide: Routine Management Tasks

Procedure 2-11 Setting Autoboot and Autosearch Flags Using the Boot Console Handler

NOTE: Starting with HP-UX 11i v3, the boot path may be specified using either the

legacy hardware path format or the lunpath hardware path format for mass storage

devices. When using the lunpath hardware path format, a few things need to be noted.

• Some elements of the lunpath hardware path (the target address and the LUN

address) may have a size up to 64 bits. The BCH interface can only handle a

maximum size of 32 bits. Therefore, all elements greater than 32 bits must be

entered in a special way. These elements must be split into two 32-bit elements

and entered as 2 elements separated by a ‘.’, for instance, the hw path

0/5/1/0.0x5000fe15001eead.0x4001000000000000 would be entered as

0/5/1/0.0x50001fe1.0x5001eead.0x40010000 (last null element omitted).

Note:ioscan -Ne can be used to generate the split form above.

• In the BCH menu, boot paths set to a lunpath hardware path will be displayed

using the split form described above.

Note: Few older systems display elements in decimal only. For these systems, the

above path would look like 0/5/1/0.13242185441.134203917.1073807360.

Users need to convert each element to HEX to recognize the target port and the

LUN address.

• The Search command in the BCH menu behaves the same way as on versions prior

to HP-UX 11i v3 and does not display any information about the lunpath hardware

paths. Therefore, in order to enter a lunpath hardware path, the user needs to

know in advance the path to enter as it cannot be selected from the Search menu.

1. After powering on or resetting your computer (or nPartition) take control of the

boot process by hitting any key on the console keyboard so that

autoboot/autosearch will not boot the system automatically (if they are

currently enabled). The Boot Console Handler will display its main menu.

The Boot Console Handler (BCH) will display its main menu and prompt for a

command:
