Error Message

Event ID: 7000 The service failed to start due to the following error:

The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.

 


 

Cause

SCSIChanger is a driver of Backup Exec for the robotic library support and depends on SCSI Mini port class.  During start of SCSIChanger, Windows 2008 R2 server requests to start all of the SCSI Mini port class device drivers and reports the startup failure even though the devices are not connected.

Solution

The messages can be ignored safely because the devices are not connected to the server.

To disable the message please perform one of following:

A) Do not install the robotic library support if a robotic library is not connected to the server.

B) Change start type of the drivers registry to 0x4 (disabled)

 

Please refer to the Microsoft KB 103000 to edit the drivers registry.
