Solution:   The ASM error "disk does not exist or is not instantiated" error can be caused by many issues:
    
     - Not disabling SELINUX:

        vi /etc/sysconfig/selinux SELINUX=disabled

        Then reboot your system and run getenforce to confirm that
        SELINUX is disabled:

        root> /usr/sbin/getenforce Disabled
