11.2.0.3 GI diskmon will be OFFLINE by default in Non-Exadata

I tested to install and upgrade for Grid Infrastructure 11.2.0.3. I had not written something about "ora.diskmon" resource. OK!!! If You installed or upgraded to GI 11.2.0.3, You will see "ora.diskmon" be OFFLINE status. Thank you @ricky_zhu - He told me: it's disabled in non-exadata env. So just ignore it.
