Step 5. When the time is appropriate, boot your system from the new kernel file
to activate your new dump device definitions. For details on how to do
that, see “Reconfiguring the Kernel (Prior to HP-UX 11i Version 2)” on
page 282.

Commands to
Configure Dump
Devices into the
Kernel
You can also edit your system file and use the config program to build
your new kernel.
Step 1. Edit your system file (the file that config will use to build your new
kernel). This file is usually the file /stand/system, but can be another
file if you prefer.
Dump to Hardware
Device
For each hardware dump device you want to configure into the kernel,
add a dump statement in the area of the file designated * Kernel
Device info (immediately prior to any tunable parameter definitions).
For example:
dump 2/0/1.5.0
dump 56/52.3.0
NOTE For systems that boot with LVM, either dump lvol or dump none must be
present! Without one of these, any dump hardware_path statements are
ignored.
Dump to Logical
Volume
In the case of logical volumes, it is not necessary to define each volume
that you want to use as a dump device. If you want to dump to logical
volumes, the logical volumes must meet all of the following
requirements:
• Each logical volume to be used as a dump device must be part of the
root volume group (vg00). For details on configuring logical volumes
as kernel dump devices, see the lvlnboot (1M) manpage.
• The logical volumes to be used as dump devices must be contiguous
(no disk striping, or bad-block reallocation is permitted for dump
logical volumes).
