[. . . ] Make sure there is not a source of bright light shining into the tape drive. The tape was written without a valid end-of-data mark, which often occurs if you power-down the tape drive while the tape drive was writing. The tape drive will perform a format recovery, which involves reading the data to determine where the end of data is located. Allow the format recovery operation to complete, and then press the eject button to unload the cartridge. Avoid power-cycling the tape drive while a tape is loaded. Factory service required Broken tape Format recovery Temperature too high Refer to "LED 4 is Flashing Orange" on page 26 for troubleshooting information. in tape path Boot block mode Reload the firmware as described in "Upgrading Firmware" on page 36. BACKUP APPLICATION IS REPORTING AN ERROR Your backup application may report an error as a result of a failure to communicate with the tape drive, a failure by the tape drive to write or read data, or because of a software configuration issue. Failure to communicate with the tape drive Communication problems on the SCSI bus may be reported by the backup application as resets, a loss of communication with the tape drive, failure to detect the tape drive, I/O device errors, or parity errors. Most often, these issues are due to SCSI cabling and termination problems. Check tape drive installation on the SCSI bus, described in "Installing the Internal SCSI Tape Drive" on page 8 or "Installing the External SCSI Tape Drive" on page 14. Use VXATool to capture the diagnostic log from the tape drive immediately after an error is reported by your backup application. Technical Support can examine the log to determine the nature of the reported error. Refer to "Capturing a Diagnostic Log" on page 31 for instructions. OCTOBER 2006 VXA-320 TAPE DRIVE 29 CHAPTER 4 TROUBLESHOOTING Failure by the tape drive to write or read data If your backup application reports a media error, one of the following situations may have occurred: The tape drive needs cleaning (see "Cleaning the Tape Drive" on page 23). If the tape drive reports an error, use VXATool to capture the diagnostic log as soon as possible after the error occurred. To ensure that the diagnostic log accurately reflects the condition of the tape drive when the error occurred, avoid disturbing the tape drive (for example, power-cycling, loading or unloading tapes, or writing or reading more data) before capturing the diagnostic log.

A filemark consists of a special recorded element within a partition, containing no user data, which provides a segmentation or location scheme for the data on the tape. Filemarks are typically used during a locate or space operation to move to a particular spot on the tape. G Gigabyte One billion bytes. H Head A device that uses induction to write a data pattern onto magnetic media and then uses either inductance or magnetoresistance to read the data back. Host Any type of computer that sends information or commands to a peripheral device, such as the tape drive. 66 PRODUCT MANUAL 433689-01 GLOSSARY I Initiator A SCSI device containing application clients that originate device service requests to be processed in a device server.
