I have a two node sql server 2008 r2 cluster that we just did an OS upgrade from windows 2008 r2 to windows 2012 r2, the OS upgrade was done in place so the SQL Server Installation stayed in tack. The cluster role won't come back online saying it's couldn't find any IP address that this instance depends on.
Everything comes on line except SQL Server resource and looking in the sql server log file it shows that error sql server is starting up as I can see master and model get started up.
From the sql log:
Could not find any IP address that this SQL Server instance depends upon. Make sure that the cluster service is running, that the dependency relationship between SQL Server and Network Name resources is correct, and that the IP addresses on which this SQL Server instance depends are available. Error code: 0x5.
Are there additional steps that need to be taken with Windows Server 2012 r2 that need to be done to get SQL Server 2008 r2 to be able to run in a failover cluster?
