    When I set the BusyRetryCount to 250 I did get a much better result, but still had a failure.

    After reading that this value in the past was unlimited, (not good either), ... I decided to increase it to 1000 on and test it.

    This did resolved te problem for me.

     

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\SCSI\Sequential&Ven_HP&Prod_Ultrium_4-SCSI\6&2f8dbc97&0&000400\Device Parameters\Storport]
    "BusyRetryCount"=dword:000003e8

    (in combination with offcourse the Symantec drivers, latetst firmware for the library and tape,... but all these where done 'before' trying the BusyRetryCount)

Hi,

 

3 things to check out:

1. Check the tapes and see if they're getting excessive Hard Write Errors. If they are, try a backup with a brand-new tape.

2. Stop the BE services, download HP Library & Tape Tools and run device checks against the robotics and the drive. Any issues with them will show up here, and if there are failures, you can log a call with HP around this.

3. Make sure there are no failed/failing HDDs on your VM hosts or the backup server...I've seen prefailure drives cause all sorts of issues.

Thanks!
