Chapter 3 Operation Using LTO Tape Cartridges 30LTO-5 Tape Drive User’s Guide Tape Cartridge Care and Maintenance Observe the following precautions to protect the data on your Ultrium tape cartridges: Always:• Remove the cartridge from the drive when not in use and store it in its protective case. • Avoid dropping the cartridge. This can damage components inside the cartridge, possibly rendering the tape unusable. If you drop a tape cartridge, open the cartridge door and make sure that the leader pin is in the correct position. • Re-tension a dropped cartridge before using. • Keep the cartridge away from: • Direct sunlight and heat sources, such as radiators, heaters, or warm air ducts. • Sources of electromagnetic fields, such as telephones, computer monitors, dictation equipment, mechanical or printing calculators, motors, magnetic tools, and bulk erasers. Do not:• Expose the cartridge to dirt, dust or moisture. • Touch the tape media within the cartridge. • Bulk erase Ultrium tape cartridges. LTO tape cartridges have prewritten servo patterns that cannot be reformatted by the tape drive. A bulk erase operation would make them unusable. • Use tape cartridges outside the specified operating conditions: 10 o C to 40o C, 20% to 80% relative humidity. If a tape cartridge has been exposed to conditions outside the specified range, recondition the tape before using in the operating environment by exposing it to the operating environment for a time equal to or greater than the time it was outside the operating environment, up to a maximum of 24 hours. Then re-tension the tape to stabilize the tape pack for better performance.
Chapter 3 Operation Data Cartridges LTO-5 Tape Drive User’s Guide31 Data Cartridges Ultrium tape drives use Ultrium tape cartridges. These are single-reel cartridges that match your drives format and are optimized for high capacity, throughput and reliability. Compatible media can be recognized by the Ultrium logo, which is the same as the logo on the front of your drive. Do not use other format cartridges in your tape drive and do not use Ultrium cartridges in other format tape drives. For optimum performance always use a data cartridge that matches the specification of your tape drive, (see table below). A lower specification will have a lower transfer speed and may not support write activities; a higher specification will not support read or write. We recommend: • Ultrium 3TB RW* and Ultrium 3TB* WORM tape cartridges for use with LTO-5 tape drives.

Chapter 3 Operation WORM Data Cartridges 32LTO-5 Tape Drive User’s Guide WORM Data Cartridges The LTO-5 tape drive includes support for both re-writable and Write- Once, Read-Many (WORM), data cartridges. WORM cartridges provide an enhanced level of data security against accidental or malicious alteration of data on the tape cartridge. The WORM data cartridge can be appended to maximize the full capacity of the tape cartridge, but the user will be unable to erase or overwrite data on the cartridge. Any attempt to modify a WORM cartridge to enable writing over existing data will result in the media becoming permanently write protected. It should still be readable in a WORM drive, depending upon the severity of the tampering, but no further appended backups will be possible. WORM data cartridges are clearly identified by their distinctive, two- tone cartridge color. They can only be used with Ultrium tape drives that support the WORM feature. LTO-5 Tape Drives and Partitioning The LTO-5 tape drive supports two tape partitions, when used with Ultrium 3TB R/W cartridges. Tape partitioning is not supported with WORM cartridges or with earlier generations of cartridge. See your backup applications documentation for more information about partitioning media. LTO-5 Tape Drives and Encryption The LTO-5 tape drive includes hardware capable of performing data encryption at full speed while writing data, and decrypting when reading. Encryption is the process of changing data into a form that cannot be read until it is deciphered, protecting the data from unauthorized access
Chapter 3 Operation LTO-5 Tape Drives and Encryption LTO-5 Tape Drive User’s Guide33 and use. LTO-5 tape drives use the strongest version of the industry- standard AES encrypting algorithm to protect your data. To make use of this feature you need: • A backup application that supports hardware encryption • Ultrium 3TB media or Ultrium 1.6TB media; no encryption will be performed when writing earlier generations of tape When should I use encryption? Your company policy will determine when you need to use encryption. For example, it may be mandatory for company confidential and financial data, but not for personal data. Company policy will also define how encryption keys should be generated and managed. Backup applications that support encryption will generate a key for you or allow you to enter a key manually. Note:Encryption with keys that are generated directly from passwords or passphrases may be less secure than encryption using truly random keys. Your application should explain the options and methods that are available. Please refer to your applications user documentation for more information. How do I enable encryption? Hardware encryption is turned off by default and is switched on by settings in your backup application, where you also generate and supply the encryption key. Your backup application must support hardware encryption for this feature to work. When will I be asked to enter the key? Encryption is primarily designed to protect the media once it is offline and to prevent it being accessed from another machine. You will be able to read and append the encrypted media without being prompted for a key as long as it is being accessed by the machine and application that first encrypted it. There are two main instances when you will need to know the key: • If you try to import the media to another machine or another instance of the backup application • If you are recovering your system after a disaster
Chapter 3 Operation Cleaning the Tape Drive 34LTO-5 Tape Drive User’s Guide What happens if I dont remember the key? If you are unable to supply the key when requested to do so, neither you nor Quantum Support will be able to access the encrypted data. This guarantees the security of your data, but also means that you must be careful in the management of the encryption key used to generate the tape. Caution:You should keep a record or backup of your encryption keys and store them in a secure place separate from the computer running the backup software. Does encryption affect tape drive performance? Hardware encryption can be used with or without compression and without speed or capacity penalties. Does the tape drive encrypt media in an earlier Ultrium format? No. Encryption is supported only on Ultrium 3TB media and Ultrium 1.6TB media. Encrypted Ultrium 3TB and 1.6TB tapes can be read on any compatible Ultrium tape drive that supports hardware encryption. LTO-5 tape drives can read Ultrium 800 GB and Ultrium 400 GB media and write Ultrium 800 GB media, but hardware encryption is not supported on these formats. Cleaning the Tape Drive Excessive tape debris or other material can accumulate on the tape heads if the drive is: • Used with non-approved media • Operated in a hot, dusty environment When this happens, the drive can:
Chapter 3 Operation Cleaning the Tape Drive LTO-5 Tape Drive User’s Guide35 • Experience excessive errors while reading or writing •The Clean LED is flashing This means that the drive needs to be cleaned. The LTO cleaning cartridge has the same dimensions as the tape cartridge and contains an LTO Cartridge Memory (LTO-CM), but is loaded with cleaning media instead of recording media. Always keep the LTO cleaning cartridge in its protective case when not in use. Procedure To clean the LTO-5 Tape Drive: 1Load an Ultrium Universal Cleaning cartridge into the tape drive. 2The drive will carry out its cleaning cycle and eject the cartridge on completion (which can take up to 5 minutes). During the cleaning cycle the orange Clean LED will be on solidly and the green Ready LED will flash. Each Ultrium universal cleaning cartridge can be used up to 50 times with Ultrium tape drives. If the cleaning cartridge is ejected immediately with the Ta p e L E D on, it has expired. Note:If the LTO-5 Tape Drive does not recognize the cartridge as an LTO cleaning cartridge, the drive stops the cleaning process and ejects the cartridge. 3After the cleaning process completes, depending on the drive configuration, either: aThe drive automatically ejects the Ultrium Universal Cleaning cartridge, or bYou must press the Eject button to eject the Ultrium Universal Cleaning cartridge. 4Write the date on the Ultrium Universal Cleaning label for future reference. Always discard used-up Ultrium Universal Cleaning cartridges.
Chapter 3 Operation Performing an Emergency Cartridge Eject 36LTO-5 Tape Drive User’s Guide Performing an Emergency Cartridge Eject If the LTO-5 Tape Drive stops communicating with the host computer, use the following procedure eject a cartridge (if necessary). Caution:When you perform an emergency cartridge eject, any data in the drive or host buffers will not be written to the tape and the tape record may not be correctly terminated with an end-of-data mark. If the end-of-data mark is not written to the tape, you will not be able to append any data to that tape unless you overwrite the existing data on the tape. To perform an emergency cartridge eject, hold down the Eject button between 5 to 15 seconds, and then release it. The tape drive firmware ignores all outstanding SCSI commands and ejects the tape.
