HP Hitachi Dynamic Link Manager Software - Manual (Page 494)

Specify the kernel used for creating an initial RAM disk image file.
Example
The following shows an execution example for Red Hat Enterprise Linux 5:
/opt/DynamicLinkManager/bin/dlmmkinitrd /boot/initrd- 2.6.18-194.el5-
hdlm.img `uname -r`
For SUSE LINUX Enterprise Server
When creating an initial RAM disk image file, you can do so without specifying
the image file name and the path for the file to be created, or you can specify
these parameters.
When omitting the parameter specification:
Use the kernel that is currently running to create an initial RAM disk
image file in the /boot directory.
The default initial RAM disk image file name for the vmlinuz-version
kernel is initrd-version.hdlm.
Example:
The name of the initial RAM disk image file for the
vmlinuz-2.6.16.46-0.14-bigsmp kernel is initrd-2.6.16.46-0.14-
bigsmp.hdlm.
-i initrd-image
Specify the name of the initial RAM disk image file to be created by using
the dlmmkinitrd utility. This parameter is used to create an initial RAM
disk image file with a name other than the default file name (initrd-
version.hdlm).
If you specify the full path of the initial RAM disk image file:
Even if you specify the -b parameter at the same time, the parameter
specification is ignored.
If you specify the relative path of the initial RAM disk image file and do
not specify the -b parameter:
The path is assumed to be the relative path from the /boot directory.
If you specify the relative path of the initial RAM disk image file and the -
b parameter:
The path is assumed to be the relative path from the location in which
the initial RAM disk image file is to be created, which is specified by
the -b parameter.
-b boot-directory
Specify the path for the location in which the initial RAM disk image file is
to be created. This parameter is used to create an initial RAM disk image
file in a directory other than the default directory (/boot).
