Chapter 3 Operation Using LTO Tape Cartridges Tape Cartridge Care and Maintenance Observe the following precautions to protect the data on your Ultrium tape cartridges: • 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 3 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 Theory This chapter describes operational theories used in the LTO-4 (Model B) HalfHeight Tape Drive. The topics covered in this chapter are: • Track Layout • Recording Method on page 37 • Data Buffer on page 37 • Data Integrity on page 37 • Data Compression on page 39 Track Layout With the LTO-4 (Model B) Half-Height Tape Drive, there are 896 data tracks on the LTO tape, numbered 0 through 895. The area between adjacent servo bands is a data band.
PAGE 52
Chapter 4 Theory Track Layout A track group is a set of tracks that is recorded concurrently. The sets of 14 data tracks in a data band are data sub-bands. There are 16 data sub-bands 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.
PAGE 53
Chapter 4 Theory Recording Method Recording Method The LTO-4 (Model B) Half-Height Tape Drive records data using writeequalized (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-4 (Model B) Half-Height Tape Drive has a 128-Mbyte buffer.
PAGE 54
Chapter 4 Theory Data Integrity Error-correction Code (ECC) 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).
PAGE 55
Chapter 4 Theory Data Compression 3 Correction: Generating corrected data from syndromes. The correction depends on the number and types of errors involved: • 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.
PAGE 56
Chapter 4 Theory Data Compression same 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.
PAGE 57
Chapter 4 Theory Data Compression • 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. Because varying types of data are encountered in normal day-to-day operating circumstances, however, an effective data compression method for a tape drive must serve various data types.
PAGE 58
Chapter 4 Theory Data Compression The LTO-4 (Model B) Half-Height Tape Drive uses a derivative of ALDC-2 lossless data compression that includes additional control codes for intelligent data compression.

PAGE 75
Chapter 6 Troubleshooting Guide Troubleshooting Suggestions 3 The method of performing tape backups can be a factor in slow backup operations. Data sent to the tape drive over a network connection and delays in data transfer over a network connection can cause backups to slow down. To determine whether the method of performing tape backups is a factor: a Use StorageCare Sage xTalk to perform a diagnostic write/read test. Caution: The read/write test will overwrite any data on the tape.
PAGE 76
Chapter 6 Troubleshooting Guide Troubleshooting Suggestions IF you believe that the read/write transfer rate is . .. acceptable, but backups still seem to be slow, THEN . . . it might be attributed to the number of files and the average size of the backup files. These factors can have a significant effect on the backup performance. Backups where the average file size is less than 200 Kbytes, for example, are slower than backups where the average file size is greater than 200 Kbytes.

Chapter 6 Troubleshooting Guide Troubleshooting Suggestions Caution: The write/read test will overwrite any data on the tape. Always use a new/blank or “scratch” cartridge for diagnostic write/read tests. IF the diagnostic test . . . THEN . . . completes normally, retry the backup operation using the same new/blank or “scratch” tape that you used for the diagnostic write/read test. If the backup retry: • Succeeds, discard the original data tape. The problem is resolved.
