When you have a primary and secondary server, that is called a cluster. There should be a cluster name that is used to access both drives. ITCM will get pointed to that cluster name. Make sure you can access that cluster name with the specific instance and port name using you Windows account and make sure that Windows account is a sysadmin for SQL, not just for the mdb.
Also if you are in the process of upgrading , why are you going to R12.9, when R14 is out and includes a few new features (updated Patch Manager) and many Testfixes that were needed for R12.9.
