Problem with create asm disk group

Question

Hi all
I am about configuring ASM, so I have downloaded the Grid infrastructure 11g (32 bit), I have configured and created parameters and directories.
I runned the installer but get stack at the 3 step where I have to change the discovery path. I have taped as path /dev where I have created 3 partitions sdb1, sdc1 and sdd1.
Is there any thing should I perform on partitions may be or parameters to set before I go through the installation?
Thanks for help

You can use the below link to install ASMLIB:
http://gssdba.wordpress.com/category/asm/
REFERANCE : Doc ID 580153.1
There are two different methods to configure ASM on Linux:
ASM with ASMLib I/O: This method creates all Oracle database files on raw block devices managed by ASM using ASMLib calls. RAW devices are not required with this method as ASMLib works with block devices.
ASM with Standard Linux I/O: This method creates all Oracle database files on raw character devices managed by ASM using standard Linux I/O system calls. You will be required to create RAW devices for all disk partitions used by ASM.
You can download the ASMLIB rpm’s from below URL:

STEP 01: LOG IN AS ROOT USER AND INSTALL THE RPMS

STEP 02: CONFIGURE ASMLIB
[root@node1 ASMLIB]# /etc/init.d/oracleasm configure
Configuring the Oracle ASM library driver.
This will configure the on-boot properties of the Oracle ASM library
driver. The following questions will determine whether the driver is
loaded on boot and what permissions it will have. The current values
will be shown in brackets (‘[]‘). Hitting <ENTER> without typing an
answer will keep that current value. Ctrl-C will abort.
Default user to own the driver interface []: oracle
Default group to own the driver interface []: dba
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]: y
