How DLTSage Error Handling Works

DLTSage is an error monitoring, reporting, and alerting technology developed by Quantum for use on SuperDLT tape drives. To receive tape drive alerts, you must use SuperDLT tape drives with DLTSage firmware.

Arcserve Backup interfaces with the firmware on SuperDLT tape drives to analyze critical tape drive and media performance parameters collected for each track, segment, Magneto Resistive (MR) channel, and optical band. Arcserve Backup uses the information collected to:

• Diagnose information such as threshold conditions and tape drive history.
• Identify high-risk tape drives and media that are approaching or have reached their end of life.
• Predict tape drive cleaning needs.
• Analyze tape drive environmental conditions.
• Generate media and hardware error messages.

Arcserve Backup queries DLTSage using a SCSI Log Sense. If a hardware or media error occurs as a backup job starts, during a backup job, or after a backup job ends, Arcserve Backup uses the information captured from the SCSI Log Sense to generate tape drive error messages that display in the Tape Log and the Activity Log. An error message displays if any of the following conditions exist:

• The tape drive is experiencing difficulties reading from or writing to a tape.
• The tape drive cannot read from or write to a tape, or the media performance is severely degraded.
• The media exceeded its life or maximum number of passes expectancy.
• The tape drive may have a clogged head or needs cleaning.
• The tape drive has a cooling problem.
• There is a potential tape drive hardware failure.

If an error condition is detected, Arcserve Backup may attempt to automatically correct the problem and complete the job.
