    MPIO log in SQL server everytime a snapshot is made

    Jason Liu Adventurer

      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.
