Chapter 4 Operation Using LTO Tape Cartridges Unloading a Tape Cartridge 4 To unload an Ultrium tape cartridge from the LTO-3 Half-Height Tape Drive, either: • Use a library or host command to unload the tape. • Press the Eject button on the front panel of the drive. Caution: Write Protecting a Tape Cartridge 4 After you press the Eject button, several minutes can elapse before the drive ejects the cartridge.
Chapter 4 Operation Using LTO Tape Cartridges Tape Cartridge Care and Maintenance 4 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.
Chapter 4 Operation Cleaning the Tape Drive 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 experience excessive errors while reading or writing, and illuminate the amber Status LED continuously during operation. This means that the drive needs to be cleaned.
Chapter 4 Operation Performing an Emergency Reset and Cartridge Eject Each time you use the LTO cleaning cartridge, the cleaning media advances to a new, unused section. After approximately 50 cleanings, all of the media will be used up and the LTO-3 Half-Height Tape Drive: • Turns on the green Activity LED • Fast flashes the amber Status LED • Ejects the LTO cleaning cartridge Always discard used-up LTO cleaning cartridges.
Chapter 4 Operation Performing an Emergency Reset and Cartridge Eject To perform an emergency reset, hold down the Eject button between 5 to 15 seconds, and then release it. IF there is . . . THEN the tape drive firmware . . . no tape in the drive, restarts the drive and begins the Power On Self Test function. a tape in the drive, ignores all outstanding SCSI commands, ejects the tape, restarts the drive, and begins the Power On Self Test function.
Chapter 5 Theory 5 This chapter describes operational theories used in the LTO-3 HalfHeight Tape Drive. The topics covered in this chapter are: • Track Layout • Recording Method on page 46 • Data Buffer on page 46 • Data Integrity on page 46 • Data Compression on page 48 Track Layout With the LTO-3 Half-Height Tape Drive, there are 704 data tracks on the LTO tape, numbered 0 through 703. Data track 703 is the track closest to the bottom edge of the tape (the reference edge).
Chapter 5 Theory Track Layout A track group is a set of tracks that is recorded concurrently. The sets of 11 data tracks in a data band are data sub-bands. There are 16 data subbands per data band. The data tracks are accessed in a serpentine manner. A wrap is a track group recorded in the physical forward or physical reverse direction. The wraps are recorded in a serpentine fashion starting in data band 0.
Chapter 5 Theory Recording Method Recording Method The LTO-3 Half-Height Tape Drive records data using write-equalized (0,13/11) Run Length Limited (RLL) code. RLL (0,13/11) Data bits are defined as follows: • ONE is represented by a flux transition at the center of a bit-cell. • ZERO is represented by no flux transition in the bit-cell. Data Buffer In its default configuration, the LTO-3 Half-Height Tape Drive has a 128Mbyte buffer. The buffer controller has a burst transfer rate of 320 Mbytes/sec.
Chapter 5 Theory Data Integrity Error-correction Code (ECC) 5 The use of Cyclic Redundancy Checking (CRC), two-level orthogonal Error Correction Coding (ECC) provides a very low probability of encountering a hard error. During the read process, ECC correction is performed on the fly without affecting tape streaming. There are two levels of Error Correction Coding (ECC).
Chapter 5 Theory Data Compression 3 Correction: Generating corrected data from syndromes. The correction depends on the number and types of errors involved: Servo-tracking Faults 5 • For one known C1 codeword pair in error in a subdata set (C2 codeword), the operation is performed by the ECC coprocessor hardware. • For two or more known C1 codeword pairs in error, the matrix is computed by firmware and the correction is performed by hardware.
Chapter 5 Theory Data Compression data to be recorded in a fewer number of bits. These codewords or symbols point back to the original data string, using fewer characters to represent the strings. Because these smaller symbols are substituted for the longer strings of data, more data can be stored in the same physical space. Some important benefits result from data compression in tape drives: • The same amount of information can be stored on a smaller length of tape.
Chapter 5 Theory Data Compression The transfer rate depends on factors such as: • Compression ratio • Drive buffer size • Host computer input/output (I/O) speed • Effective disc speeds of the host computer • Record lengths that the host computer transmits Data compression algorithms can be tailored to provide maximum compression for specific types of data.
Chapter 5 Theory Data Compression Software data compression should never be used because the built-in intelligent data compression of the LTO-3 Half-Height Tape Drive is much more efficient than software data compression. The LTO-3 Half-Height Tape Drive uses a derivative of ALDC-2 lossless data compression that includes additional control codes for intelligent data compression.

Chapter 7 Troubleshooting Guide Troubleshooting Suggestions Slow Backup Operations 7 Many factors can make backups appear to be slow. To achieve the highest possible transfer rate, the LTO-3 Half-Height Tape Drive: • MUST be attached to a Low Voltage Differential (LVD) SCSI controller capable of a minimum of 80 Mbytes per sec., and • MUST NOT share the same SCSI bus as another active SCSI device such as hard drives. 1 Verify that the tape drive is attached to an LVD SCSI controller.
Chapter 7 Troubleshooting Guide Troubleshooting Suggestions 2 If the tape drive is attached to an LVD SCSI controller, verify that it does not share the SCSI bus with another active SCSI device by: • • Checking: • Windows Device Manager • Unix/Linux logs Monitoring the SCSI controller activity during system startup. IF the tape drive . . . THEN . . .
Chapter 7 Troubleshooting Guide Troubleshooting Suggestions b When the test finishes, determine the megabytes per second data transfer rate to verify that the tape drive is performing at an acceptable rate. IF you believe that the read/ write transfer rate is . . . too slow, THEN . . . use the tape diagnostic software to perform a trace buffer retrieval. Send the diagnostic output file to Technical Support for evaluation of the SCSI bus condition.
Chapter 7 Troubleshooting Guide Troubleshooting Suggestions The following subsections provide troubleshooting guidelines for dealing with the most common TapeAlert error conditions. 7 Backup Failure TapeAlert Messages A number of problems can cause a backup operation to fail.
