Event ID 15 is reported during a cleaning job
Event ID 15: The device, \Device\Scsi\adpu160m1, is not ready for access yet.
The tape drive becomes a busy state for a long term while a cleaning media is installed on the drive. This is the reason for the event ID 15.
If the event ID 15 is ONLY reported during a cleaning job, this is normal behavior. You can ignore the event message.
Note: Event ID 9 may be reported if you are not using the latest firmware of the drive.
