Assume that you save your database files in Azure Premium Storage. When you run DBCC CHECKDB on the database in SQL Server 2014, you may receive error messages that resemble the following:

Msg 1823, Level 16, State 2, Line 3
A database snapshot cannot be created because it failed to start.

Msg 1823, Level 16, State 8, Line 3
A database snapshot cannot be created because it failed to start.

Msg 5120, Level 16, State 147, Line 3
Unable to open the physical file blob_storage_URL_path. Operating system error 24: "24(The program issued a command but the command length is incorrect.)".

Msg 7928, Level 16, State 1, Line 3
The database snapshot for online checks could not be created. Either the reason is given in a previous error or one of the underlying volumes does not support sparse files or alternate streams. Attempting to get exclusive access to run checks offline.

Msg 5030, Level 16, State 12, Line 3
The database could not be exclusively locked to perform the operation.

Msg 7926, Level 16, State 1, Line 3
Check statement aborted. The database could not be checked as a database snapshot could not be created and the database or table could not be locked. See Books Online for details of when this behavior is expected and what workarounds exist. Also see previous errors for more details.
