ASMLIB for RHELAS3.0

Question

Does the continued absence of ASMLIB for RHEL AS 3.0 mean that automatic storage management is unavailable for this platform?
I have found very little mention of anyone using ASM on linux. Does the installation of Oracle on the ext3 file system remain the most common installation? I found it interesting, for example, that the file system install is the only installation type mentioned in guides such as on puschitz.com

Can you help me?
I use RHAS 2.1 and my system didn't recognize raw device.
[root@node2 root]# /etc/init.d/oracleasm createdisk vol1 /dev/raw/raw20
Marking disk "/dev/raw/raw20" as an ASM disk [FAILED]
[root@node2 root]#
When I use /dev/sdd1 as a vol1 disk:
[root@node2 root]# /etc/init.d/oracleasm createdisk vol1 /dev/sdd1
Marking disk "/dev/sdd1" as an ASM disk [  OK  ]
all is Ok... but I can't create a diskgroup from a ASM instance:
SQL> CREATE DISKGROUP dgroup_01
2 DISK '/dev/oracleasm/disks/vol1';
CREATE DISKGROUP dgroup_01
ERROR at line 1:
