    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

    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.
