Sometimes it is necessary to collect tape drive trace when diagnosing failed tape backups to do this enable tape trace as follows:

cluster1::> storage tape trace -node <nodename> -is-trace-enabled true

more info on tape diagnostics see NetApp kb below:

 
http://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.dot-cm-cmpr-960%2Fstorage__tape__trace.html
