Hi EE,

An upgrade to SQL server 2012 SP4 has failed, context:

I'm patching a 2 node AG cluster the first patch has been applied to secondary node successfully:

I then failed over the secondary node.  Then I began patching primary node:

The primary node patch failed I have got no idea why it failed and the SQL instance is no longer accessible.

I restored from a VM snapshot, tried it again and got the same error.  

Looking at these error log files I can't make sense of what went wrong.

Any assistance is appreciated.

Thank you
