          according to thalai muthu Step by Step Oracle ASM Disk creation on Linux

          muthu is doing all this on /dev/sdb ( which is mostly second scsi device ).

          in my vmware i have only one hard drive /dev/sda how i can create partiton on that with fdisk ??

            on my vmware i am doing practice to move database from fil system -------------> ASM

            database is 10gR2 and OS is RHEL 5.3 (32 bit ).

            first of all i installed ASMlibrary with these rpm :

            Login as ROOT
            # rpm -Uvh oracleasm-support-2.1.3-1.el5.i386.rpm
            # rpm -Uvh oracleasm-2.6.18-128.el5-2.0.5-1.el5.i686.rpm
            # rpm -Uvh oracleasmlib-2.0.4-1.el5.i386.rpm

            then i followed muth oracle dba blog :

            http://muthuappsdba.blogspot.in/2012/03/step-by-step-oracle-asm-disk-creation.html

            problem i was facing is that i had only one SCSI drive attached to my vmware.

            i shutdown virtual machine and two IDE hard drives .

            then i power on virtual machine and partitioned those two newly attached hard drives

            fdisk /dev/hda1
            fdisk /dev/hdb1

            then i succeeded to create two asmdiskgroups.

            oracleasm createdisk DISK01 /dev/hda1
            Writing disk header: done
            Instantiating disk: done

            [root@oem opt]# oracleasm createdisk DISK02 /dev/hdb1
            Writing disk header: done
            Instantiating disk: done

              osama acccording to your blog i am creating flash ecovery area to move to asm file system :

              alter system set db_recovery_file_dest=’+DISK01';
              alter system set db_recovery_file_dest=’+DISK01'
              *

                Please its not tutorial Forum stop post every steps try to read something stop post everything you are doing you don't know anything about ASM and you trying to create one you don't know how to change parameter and you try before reading its not just step to apply you have to know what you do

                READ ORACLE DOCUMENTATION
                alter system set DB_RECOVERY_FILE_DEST='+DATA' scope=both;
                Read and stop post

                  Hi,

                  You don't seem to have a value for the asm_diskstring parameter in your ASM init.ora file at the first place.
                  Please put the correct value for that parameter where your disks can be discovered, then start the ASM instance and try to create the diskgroups.
