DbStorageLocation Element
SQL Server 2012
Specifies the folder where Analysis Services creates and manages all the database data and metadata files.
The DbStorageLocation database property must be set to an existing UNC folder path or an empty string. An empty string is the default server data folder. If the folder doesn't exist, an error will be raised when executing a Create, Attach, or Alter command.
In addition, the DbStorageLocation database property cannot be set to point to the server data folder or any of its subfolders. If the location points to the server data folder or any of its subfolders, an error will be raised when executing a Create, Attach, or Alter command.
