The special file created by the device driver for tracing purposes could not be opened by the server. This file should be created when the device driver is configured on the system
Device driver tracing could not be started.
Make sure that the special file exists and can be accessed by the server. If the device driver has not been completely configured and special files created for all devices, do so. The device driver can also be traced by specifying the name of a library or drive that has been defined to the TSM Server.
