Database Software

Hi ,
I have created a virtual machine of around 50gb and on that i have added 4 harddisk of around 3gb after that i have mount those disk and created folders accordingly i have installed OLE 5.5 and oracle 10g relaease 2 above things i have done for ASM for asm configuration . now the above are copy and paste from virtual machine
I have added 4 machines mount them created folders on them naming asm1,asm2,asm3,asm4 and created raw devices in them with the help of dd command of 3 gb files each .....after that i relate them losteup devices and raw devices and later on as chage the owner and permissions related to oracle .......... at the time the owner changed to oracle so i created my asm instance with one diskgroup and normal redundancy ......but when i reboot my machine started the following asm instance I got the following error .........

ASM Cache 25165824 bytes
ORA-15032: not all alterations performed
ORA-15063: ASM discovered an insufficient number of disks for diskgroup "DATA"

later on i came to know that it is not able to getthe disk which i created and the cause is the owner has become root so that 's the major cause i was not able to get my diskgroup so i changed the owner and permssions granted to oracle and at that time it has changed but when reboot of machine makes it root user so iam not able to configure it becasue when surfing these are the commands

chown oracle:dba /dev/raw/raw1
# chown oracle:dba /dev/raw/raw2
# chown oracle:dba /dev/raw/raw3
# chown oracle:dba /dev/raw/raw4

# chmod 660 /dev/raw/raw1
# chmod 660 /dev/raw/raw2
# chmod 660 /dev/raw/raw3
# chmod 660 /dev/raw/raw4

but after reboot owner becomes root and coz of this iam not able to access my diskgroup iam pasting output of certain things
