I am installing a 2012 SQLServer clustered instance on a pair of Windows 2008 R2 servers. I have shared drives mounted on the servers using SAN storage. These drives are all assigned labels and drive letters and show as available in server manager as a cluster resource. They are not in any other cluster group. I have run the SQLServer cluster preparation and all checks and prechecks I know to do pass. When in the install, in the Database Engine Configuration page, when I specify the data directories I want I get these errors, it seems on just one of the drives involved:
The volume that contains SQL Server data directory R:\MSSQL11.MSSQLSERVER\MSSQL\Data does not belong to the cluster group.
I have volumes E: (for binaries), S: (for data), R: (for logs) and Y: for on disk backups. I only see this error for drive R: but I don't see any issue with it.
What can I tell my windows admin to look for or change to proceed with installation?
