Cannot Access Exchanger Control Device on Windows

 

2000/XP/Server 2003

 

Data Protector uses the SCSI mini-port driver to control backup drives

 

and libraries. Data Protector may fail to manage devices if other device

 

drivers are loaded on the same system. The error message Cannot

 

access exchanger control device appears when device operations

 

such as media formatting or scanning are started.

Action

Run the <Data_Protector_home>\bin\devbra -devcommand on the

 

system where the devices are located, to list all physical devices that are

 

configured on the system. If any of the SCSI addresses have the CLAIMED

 

status value, they are used by another device driver.

 

Disable the Windows 2000/XP/Server 2003 robotic driver. For detailed

 

steps, refer to the online Help index keyword “robotics drivers”.
