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

The oracleasm script fails if SELinux is in Enforcing mode. The suggested workaround is to disable the SELInux policy module for Oracle ASM before running oracleasm:
# semodule -d oracleasm
# semodule -l | grep oracleasm
oracleasm 1.0.0 Disabled
