NOTE: Version 2.x volume groups do not support dump logical volumes.

This section describes LVM information about using logical volumes as dump devices. For information on configuring and managing dump devices, see HP-UX System Administrator's Guide: Overview.

Creating a Dump Logical Volume

To create a dump logical volume, use the lvcreate command. You must set a contiguous allocation policy using the -C y option and disable bad block relocation using the -r n option. For example:

# lvcreate -C y -r n -n dump_lvol /dev/vgnn

For more information, see lvcreate(1M).

After creating a logical volume to be used as a dump device, use the lvlnboot command with the -d option to update the dump information used by LVM. If you created a logical volume /dev/vg00/lvol2 for use as a dump area, update the boot information by entering the following:

# lvlnboot -d /dev/vg00/lvol2

Removing a Dump Logical Volume

To discontinue the use of a currently configured logical volume as a dump device, use the lvrmboot command with the -d option. For example:

# lvrmboot -d /dev/vg00/lvol2

You can then use the logical volume for other purposes. To remove the logical volume completely, see “Removing a Logical Volume”.
