bootconf(4) Kernel Interfaces Manual bootconf(4) NAME
bootconf - boot device configuration table DESCRIPTION
The file contains the address and disk layout type of the system's boot devices or lif volumes. It is used by the and HP-UX kernel control scripts (fileset to determine how and where to update the initial boot loader. Normally the kernel's script queries the system's hardware and creates the file. In rare cases when either the system configuration cannot be automatically determined or additional and/or alternate boot devices should be automatically updated, the administrator must edit the file manually. There is one line in the file for each boot device. Each line contains the following blank-separated fields in the order shown: disk type A flag indicating how the file system(s) on the disk are laid out. The flag must be one of the following: Indicates that the root disk is in LVM or VERITAS Volume Manager (VxVM) format. If LVM or VxVM mirrors are used, then each of the "mirrors" must have its own line in the file. Indicates that the root disk is in the "whole disk" format with no partitions, but boot and swap space are reserved outside the file system. device file The absolute path of the device special file that accesses the physical device where the boot area is located. For LVM root disks, the device special file is the physical volume(s) returned by the command. For "whole disks" this is the device file that references the entire disk. Blank lines are permitted. Any line beginning with a is considered to be a comment. DIAGNOSTICS
The Software Distributor log file contains diagnostic messages under the fileset if the file is incorrect. Most of the messages are self- explanatory; a few warrant additional explanation: If there are no other messages about the file is probably empty. Otherwise, the file is not in the proper format, and the other messages will explain what the problem is. The specified device file does not point to a disk where there is a lif which contains the file Some character other than or is in the first field of a line. As of release 10.0, the boot areas in must all be on the same type of disk layout. There are characters after the device file specification. EXAMPLES
The boot area is on an LVM root disk: l /dev/disk/disk7_p2 The boot area is on a whole disk layout: w /dev/disk/disk7 WARNINGS
All of the boot devices in the file must have the same disk layout. AUTHOR
