Boris, Library managed encryption is controlled by the TS3500 library communicating with the Encryption Key Manager application and TSM has no awareness of any encryption occurring. No TSM configuration is required when performing library managed encryption. I strongly recommend that you review the the following: IBM Encryption Key Manager Intro, Planning and User Guide (GA76-0419) IBM Tape device Drivers Encryption Support (GA32-0565) IBM TSM Building a Secure Environment (Redbook SG24-7505) IBM System Storage TS1120 Tape Encryption: Planning, Implementation and Usage Guide (Redbook SG24-7320) IBM Tape Encryption for TS1120 and IBM Ultrium 4 Tape Drives (TechDoc, Rolf Hahn)
Plan to spend a few weeks setting up your key management, testing and documenting key management policies and procedures. Also verify the recovery procedure if you accidently loose or destroy a key (hint - monster.com) An advantage to library managed encryption is that your security group can be respoonsible for managing the encryption keys with almost no TSM expertise required. Additionally, a different application (not TSM) could write encrypted data to a tape with no dependence on TSM (other than temporarly marking that drive unavailable and ensuring the tape is not a TSM tape). Have you considered encrypting every tape in the library? It may simplify your media management. The performance hit of encrypting on a TS1120 is almost nill.

Boldness has genius, power and magic. -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Herrmann, Boris Sent: Tuesday, April 15, 2008 7:41 AM To: ADSM-L@VM.MARIST.EDU Subject: [ADSM-L] Drive Encryption (3592) Hello, again, I've a question regarding drive encryption. Our environment: TSM Server 5.4.1.2 (AIX 5.3) TS3500 tape library with 3592 Drives In the next time, our old 3592 Drives will be replaced with newer one (3592) which have the hardware drive encryption capability. Our plan is to use the encryption only for our COPYSTORAGE POOLS , TSM DB BACKUPS and EXPORTS (using "library encryption" method). We want to create two DEVCLASSES: DEV3592 and DEV3592_ENC If I understand the option DRIVEEncryption correctly it is not possible to use both (TAPEPOOL without encryption) and (COPYPOOL with encryption) because either one will fail with "library method"?. If we use ALLOW for DEV3592_ENC => encryption will work (for our COPYPOOLS). But when we use OFF for our DEV3592 (TAPEPOOL) => backup will fail with method Library Encryption? So how is it possible to use both? Any help or tips are appreciated. With kind regards, Boris IMPORTANT: E-mail sent through the Internet is not secure.
