During the normal tape operations, the process is failing.  Examining the logs it seems that scandrive operations, initiated by actor service, is interrupting the tape operations
This is happening in conjunction with IBM tape drives.

In logs you can see:

The restore request is using Tape2 for restore:

03/03/18;00:48:53;1270237;32;New DeviceDrive(Tape2,Tape2);;;;
03/03/18;00:48:53;1270237;32;Open drive Tape2 type IBM-LTO5;;;;
03/03/18;00:49:03;1270237;6;Reserve device;
03/03/18;00:49:03;1270237;32;Open drive Ok;;;;

Scandrive is initiated for Tape2

03/03/18;00:49:59;0;12;Check \\.\Tape2;
