Hat Enterprise Linux AS4/ES4 or SUSE LINUX Enterprise Server, use the
raw command to create the character-type device file.
The following shows the difference between these two methods:

Use the udev rule file to create a character-type device file.
To create a character-type device file by using an udev rule file:
1 Edit the /etc/udev/rules.d/60-raw.rules file.
.
For example, you might edit the file as follows:
ACTION=="add", KERNEL=="sddlmaa", RUN+="/bin/raw /dev/raw/raw1
%N"
2 Restart the host or execute the start_udev command.
.
The editing performed in step 1 is applied when the host is restarted or
the start_udev command is executed.
The following shows an example of executing the start_udev command:
# /sbin/start_udev

Enterprise Server
A character-type device file is created from the HDLM device using the Linux
raw command. The following is an example of executing the raw command for
an HDLM device.
In this example, the command creates /dev/raw/raw1 as a character-type
device file for /dev/sddlmaa (major number of 253, minor number of 0).
Creating File Systems for HDLM (When Volume Management
Software Is Not Used)
This section describes how to build a file system in an HDLM-managed device
without using volume management software.

The character-type device file created by using the raw command is
deleted when the host is restarted.
The character-type device file created by using an udev rule file is not
deleted when the host is restarted.
