3714.0. "Backup Exec 6.11 (NT4.0) fails to Sony SDT 7000 drive" by OSLLAV::BJARNEC_P (The last boat left without me .....) Fri Apr 04 1997 17:29

    Hi,
    
    Hope someone can help with this one ...
    
    Prioris XL 5200
    Sony SDT 7000 tape drive (= TLZ09?) - internal drive
    Windows NT 4.0-SP2 Server (no Hotfixes)
    Backup Exec 6.11, build 184
    Sony SDT 7000 tape driver for NT/Intel
    
    Backup Exec fails intermittently, that is; it almost always fails (9
    out of 10 times ....) but not always at same stage of backup.  Fails
    both when backing up with HW or SW compression.  Backup without
    compression enabled completes, no problem!
    
    
    Error message in Event Viewer:
    
    -> Source: Backup Exec 6.11.   The device \device\tape0 has a bad block
    
    -> (in backup log file "Bad data, tape ... has a bad block).
    
    
    I have had him test Windows NT Backup, too.  NT Backup succeeds with HW
    compression enabled (have not tested without HW compression)!!!
    
    The customer has also tried a couple of other things, without any
    better result:
    
    -> He set SCSI transfer rate from 10MB to 5MB
    -> ---"-----   Sync Negotiation from YES to NO
    
    
    Questions:
    ---------
    
    - Has anyone else seen this problem?  
    - Is it a bug in Backup Exec? 
    - Is there a fix? 
    - Should we ask the customer to change to change to some other Backup
      application?
    
    All help very much appreciated!!!
    
    Cheers,

Please log an IPMT case against the TLZ09 for this.

We will need the rest of the entry from the Event Log.

re .1


	If this is a Sony SDT-7000 don't log an IPMT aginst the 
TLZ09. They are not the same and Storage will reject the IPMT.
If it is a SDT-7000 you need the FRxxxx part number to log the
call aginst. This is serviced by the PCBU.

    Hi folks!
    
    Thanks for repling to my note!!  I was away last week, but has been
    informed that BackupExec (and also later NT backup!!!) failed due to a
    HW problem with the tape drive.  After changing the drive both
    BackupExec and NT Backup complete without an error message.
    
    Thanks!
