A netbackup upgrade won't help you with status code 84. There are 4 type of reason for status code 84
- Bad media or bad tape drives - Check for SCSI sense keys, they can assist you in locating the problem.
- Tape drive firmware problem - Is the tape drive firmware up to date ?
- Connection related issue (SCSi or SAN related)
- Dust
Long time ago I used a tool called "scsitool box ". With that tool you can run a series of test to establish the quality of drive/media. HP also provide a tool called "HP StorageWorks Library and Tape Tools" it may do the same job.
If you are on Linux, sg_logs can do the job:
sg_logs -p=2 /dev/nst0
HP Ultrium 3-SCSI L29S
Write error counter page
Errors corrected without substantial delay = 52
Errors corrected with possible delays = 0
Total operations = 0
Total errors corrected = 0
Total times correction algorithm processed = 58
Total bytes processed = 723
Total uncorrected errors = 0
congo:/usr/bin # sg_logs -p=3 /dev/nst0
HP Ultrium 3-SCSI L29S
Read error counter pageg
Errors corrected without substantial delay = 5
Errors corrected with possible delays = 0
Total operations = 0
Total errors corrected = 0
Total times correction algorithm processed = 5
Total bytes processed = 61
Total uncorrected errors = 0
