I have 2 new servers installed with SQL2008r2 and Windows 2012. This is a supported configuration.

Twice we have had strange issues with the disk in the SQL resource disappearing from the Resource Group. I am only asking to get an idea if others installing 2008 SQL on Windows 2012 have had any issues.
I should also say the server is using EMC Powerpath.
I don't always test my SQL scripts, but when I do, I test in Production.
