Red Hat Enterprise Linux is fully equipped with the administration tools to set up raw devices and administrate them during system start. To set up a Red Hat Enterprise Linux system the partitions are administrated in the file /etc/sysconfig/rawdevices.
This is a plain text file contains comments and examples for possible configurations, as follows:
# raw device bindings# format: rawdev major minor # rawdev blockdev # example: /dev/raw/raw1 /dev/sda1 # /dev/raw/raw2 8 5
/dev/raw/raw1 /dev/sdd1 /dev/raw/raw2 /dev/sdd2 /dev/raw/raw3 /dev/sdd3 /dev/raw/raw4 /dev/sdd4
Once created, you need to bind the raw devices. This can be done by starting them from /etc/rc.d/init.d/rawdevices.
[root@legolas init.d]# cd /etc/rc.d/init.d[root@legolas init.d]# sh rawdevices startAssigning devices:/dev/raw/raw1 --> /dev/sdd5 /dev/raw/raw1: bound to major 3, minor 5/dev/raw/raw2 --> /dev/sdd6 /dev/raw/raw2: bound to major 3, minor 6/dev/raw/raw3 --> /dev/sdd7 /dev/raw/raw3: bound to major 3, minor 7/dev/raw/raw4 --> /dev/sdd8 /dev/raw/raw4: bound to major 3, minor 8
done
To guarantee that the raw device binding occurs during any restart, use the chkconfig(8) utility.
# /sbin/chkconfig rawdevices on
