Abstract

Hardware and Volume Statistical Analysis and Reporting System for Detecting and Isolating Media and Hardware Errors on the Magstar Family of Tape Drives In tape libraries and data processing centers, even a few bad tapes can cause many problems. One problem is that these tapes exhibit temporary and/or permanent errors during reading and/or writing. These errors reduce system throughput and jeopardize the integrity of the data on the tape. Another problem is that bad tapes sometimes deposit debris on the heads of the tape drives in which the tapes are mounted. Subsequently, this debris is then deposited on other tapes, which then deposit the debris on to heads of other tape drives, etc. When enough debris accumulates on the head of a tape drive, the drive exhibits temporary and/or permanent errors during reading and/or writing of tapes. As stated above, these errors reduce system throughput and jeopardize the integrity of the data on the tape. Furthermore, customer service engineers must then clean the heads of tape drives in which the bad tapes were mounted. This is a time consuming, manual process which costs the customer money, both for a service call and system down time.
