In addition - in case of using TDP for Oracle you can inspect TSM Server logs 
for TDP nodes. I think for other TDPs it is the same.
Be careful with encryption for TDP backups - some additional configuration 
efforts are required .

Subject: Re: [ADSM-L] Verifying IBM TSM Encryption types

TSM client encryption can be verified per IBM Technote 1303197.
Tape drive encryption is a hardware topic addressed by the documentation for 
the particular drive model, as in recent 3592 model variants.
