We use the 3PAR disk subsystem with servers connected via Qlogic to a SAN.  We perform nightly snapshots where the snapshot disk (target/LUN) is temporally removed (2 minutes) from Windows.  The disk is updated and then added back to Windows.  We use DiskPart to rescan the disks to make Windows "notice" the changes.  We have the following two errors nightly in the system event log:

Source: LDMS
Event ID: 3014
Description: Unhandled exception, exception code=6BE.

Source: VDS Basic Provider 1.0
Event ID: 1
Description: Unexpected failure. Error code: 2@0101002D

Does anyone have any information on these errors?

The Virtual DMA Service service controls the controller connection to the server. The controllers are using their own DMS controller as opposed to the predefined DMA channel on the system board. You should contact the vendor to see if they offer a BIOS upgrade or any additional troubleshooting tips. This is happening because there are buffer inconsistencies the server and the storage controllers.
