Managing Tape Drives Using DLTSage Error Handling, Understanding How DLTSage Error Handling Works

Page 158 highlights

The Device Manager Managing Tape Drives Using DLTSage Error Handling 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. BrightStor 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. BrightStor 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. Understanding How DLTSage Error Handling Works BrightStor 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, BrightStor 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 umber 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, BrightStor ARCserve Backup may attempt to automatically correct the problem and complete the job. However, you must install the BrightStor ARCserve Backup Tape and Optical Library Option to use BrightStor ARCserve Backup's uninterrupted inline cleaning, drive usage balancing, and error-preventive drive selection features. For more information about automated error resolution, see the BrightStor ARCserve Backup Tape and Optical Library Option Guide. 7-10 Administrator Guide

Managing Tape Drives Using DLTSage Error Handling
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.
BrightStor 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.
BrightStor 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.
Understanding How DLTSage Error Handling Works
BrightStor 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, BrightStor 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 umber 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, BrightStor ARCserve Backup may attempt to
automatically correct the problem and complete the job. However, you must
install the BrightStor ARCserve Backup Tape and Optical Library Option to use
BrightStor ARCserve Backup’s uninterrupted inline cleaning, drive usage
balancing, and error-preventive drive selection features. For more information
about automated error resolution, see the
BrightStor ARCserve Backup Tape and
Optical Library Option Guide.
