MPIO log in SQL server everytime a snapshot is made

I keep seeing these events every time a snapshot is made on Nimble for the SQL server:

Events ID 1:

\Device\MPIODisk### created.


And once in a while it will give me some warnings and errors like this:


A Single Path Fail-Over is being attempted on \Device\MPIODisk###


Microsoft DSM failed to return a Path to \Device\MPIODisk###


The device, \Device\Harddisk#\DR###, is not ready for access yet.


The SQL server is a Windows 2008 R2 VM on a Windows 2012 cluster. The version of the SQL server is SQL 2008 R2.

Everything seems to be working fine for the SQL server, but I just want to know what those events and warnings and errors are about. Thanks.
