2.2.23 Oracle Clusterware Fails to Start on ASM Storage with SELinux Enabled

If the SELinux policy packages have not been updated recently, Cluster Ready Services (CRS) might fail to start with messages such as the following in /var/log/messages:

SELinux is preventing /usr/lib/oracleasm/oracleasm-instantiate-disk from
associate access on the filesystem DATA1.

The solution is to upgrade the selinux-policy and selinux-policy-targeted packages to ensure that you are running a version no earlier than

# yum update 'selinux-policy*'

After upgrading the packages, reboot the system. (Bug ID 13925445)
