Notes:
• The contents specified in the dlmsetopt utility are written to the options

editor such as vi. The following table lists the names of conf files used by
the dlmsetopt utility.
Table 7-8 conf files used by the dlmsetopt utility

• If you use the dlmsetopt utility in an environment where an HDLM device
is used for the boot disk, after changing the settings, you need to re-
create the initial RAM disk image file. To re-create the file, use the dracut
command for Red Hat Enterprise Linux 6, and the dlmmkinitrd utility for
supporting a boot disk for other OSs. If you change the name of the initial
RAM disk image file, change the settings file for the boot loader so that
the re-created initial RAM disk image file is used during boot-up. For
details on this procedure, see the following table.
Table 7-9 Setting file names for boot loaders
Boot loader File Name
LILO
/etc/lilo.conf
GRUB For Red Hat Enterprise Linux
/etc/grub.conf
For SUSE LINUX Enterprise Server
/boot/grub/menu.lst
ELILO
/etc/elilo.conf
• When you specify the -prsup on parameter, you need to restart the host
to enable the setting. To link with Lifekeeper, do not set the -prsup on
parameter.
