3. If these measures do not correct the problem, contact Dell customer support.Resolving Media-Related ProblemsTo resolve problems that are related to media, the tape drive's firmware includes:v Test Cartridge & Media diagnostic that verifies whether a suspect cartridge andits magnetic tape are acceptable for use.v Statistical Analysis and Reporting System (SARS) to assist in isolating failuresbetween media and hardware. To determine the cause of failure, SARS uses thecartridge performance history that is saved in the cartridge memory (CM) andthe drive performance history that is kept in the drive's Vital Product Data(VPD) area in Non Volatile Random Access Memory (NVRAM). Any failuresthat SARS detects are reported as TapeAlert flags on the system (see Table 5-5 onpage 5-17).If you encounter a media-related problem, use the following procedure:Notice: When you run the Test Cartridge & Media diagnostic, data on the suspecttape is overwritten. If valuable data is on the tape, be sure to copy thedata before running this test.1. If possible, run the tape cartridge in a different tape drive. If the operation inthe other tape drive fails and 6 or 7 displays, replace the media. If theoperation succeeds, run the Test Cartridge & Media diagnostic (see FunctionCode E in “Selecting a Diagnostic or Maintenance Function” on page 5-1).2. If the Test Cartridge & Media diagnostic fails, replace the media. If it runssuccessfully, clean the tape drive and run the tape drive diagnostics (see the“Cleaning the Tape Mechanism” on page 3-7 section and Function Code 1 in“Selecting a Diagnostic or Maintenance Function” on page 5-1).3. If the tape drive diagnostics fail, contact Dell technical support.
