I. ASSUMPTION.
--------------
SuSE Linux SLES 8
Oracle Server Version 10.1.0.2.0                                        
Storage : ASM Disks groups on Raw Devices                                   
Owner : oracle1010
Group : dba


II. ACTIONS.
------------

1. Create disk partitions (without format/file system defined)
Eg : 4 partitions of 250Mb each : /dev/sda6 to /dev/sda9


2. Bind Raw Devices
a) Automatic bind on machine startup
Fill de /etc/raw file :
raw6:sda6
raw7:sda7
raw8:sda8
raw9:sda9

Enable Raw service : chkconfig raw on 
Check with :  chkconfig | grep raw
Or /etc/init.d/raw start to enable it now if no reboot desired for the moment

b) Manual bind
raw /dev/raw/raw6 /dev/sda6
raw /dev/raw/raw7 /dev/sda7
raw /dev/raw/raw8 /dev/sda8
raw /dev/raw/raw9 /dev/sda9

Check with : raw -qa


3. Set ownership and permissions to Oracle kernel owner
chown oracle1010:dba /dev/raw/raw6
chown oracle1010:dba /dev/raw/raw7
chown oracle1010:dba /dev/raw/raw8
chown oracle1010:dba /dev/raw/raw9

chmod 660 /dev/raw/raw6
chmod 660 /dev/raw/raw7
chmod 660 /dev/raw/raw8
chmod 660 /dev/raw/raw9


4. Creation via DBCA of the database V1010ASM
If no ASM instance exists on the machine it will be also created (instance +ASM)
At the end you  should have the instances :
 +ASM     : ASM instance
 V1010ASM : Database instance


5. Connection to +ASM instance
export ORACLE_SID=+ASM
sqlplus "/ as sysdba"
select * from v$asm_disk     ;
select * from v$asm_diskgroup;
select * from v$asm_file     ;
select * from v$asm_alias    ;
select * from v$asm_template ;
select * from v$asm_operation;
select * from v$asm_client   ;


6. Connection to V1010ASM instance
export ORACLE_SID=V1010ASM
sqlplus "/ as sysdba"
select * from v$asm_disk     ;
select * from v$asm_diskgroup;
select * from v$asm_file     ;
select * from v$asm_alias    ;
select * from v$asm_template ;
select * from v$asm_operation;
select * from v$asm_client   ;
