Using HP-UX Commands to Configure Dump Devices into the HP-UX Release 11i Version 1.5 Kernel

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:

	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:

To use logical volumes for dump devices (regardless of how many logical volumes you want to use), include the following dump statement in the system file:

Configuring No Dump Devices

To configure a kernel with no dump device, use the following dump statement in the system file:

	NOTE: If you truly want no dump device to be configured into the kernel, you must use the above statement (dump none). Omitting dump statements altogether from the system file will result in a kernel that uses the primary paging device (swap device) as the dump device.

Once you have edited the system file, build a new kernel file using the mk_kernel command (see "Steps to Perform Whole Kernel Configuration Using HP-UX Commands" in the white paper Reconfiguring the Kernel in HP-UX Release 11i Version 1.5 for details on how to do this).

Perform a kernel update using the kmupdate command (see "Steps to Perform Whole Kernel Configuration Using HP-UX Commands" in the white paper Reconfiguring the Kernel in HP-UX Release 11i Version 1.5 for details on how to do this)

Reboot your system to activate your new dump device definitions.
