I have been thinking through different CUCM failure scenarios.  Is it possible to promote a subscriber to be a publisher in the event of say a hard disk failure in the publisher?

Not possible Amigan, not in this version at least. Not aware if newer releases can.

Remember that while running without the Publisher, few things are actually down, if fault tolerance has been configured across. For example, a CTI application relying on the Publisher may fall back to a subscriber and all should be good. Its only writing changes on the database what actually gets limited. Call processing and services can still be made available.

Thank you.  The main thing that is only on the Publisher is that it serves the Proxy Phones and it's the tftp server.
