6. Repeat steps 1–5 to create four partitions for raw device I/O.

7. Verify the setup using p to print the full partition table before writing it out. Make sure that there are no

You can now write this partition table to disk and quit the fdisk(8) utility.

9.6.3 Administering Raw Devices

Administer raw disk partitions using a plain text file that contains comments and examples for possible

configurations.

Procedure

● If you are using a Red Hat Enterprise Linux system running release 3 or 4:

a) Administer the partitions using the /etc/sysconfig/rawdevices file:

# 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

b) Create the raw devices.

c) Bind the raw devices 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 start

Assigning 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
