SQL/ Oracle Application backup streams are failing with error code 6 while writing on VTL

[Tanmoy1]

Hi All,

Some of our SQL/ Oracle Application backup streams are failing with error code 6 while writing on VTL. However when changing it to use same DataDomain as DDBoost disk, its woring fine.

Master Server : 7.6.0.1
Master Server OS : Win 2K8 R2

Error:

4/29/2016 7:30:51 PM - Error bptm(pid=8268) error requesting media, TpErrno = File name already exists   
4/29/2016 7:30:51 PM - Warning bptm(pid=8268) media id D06674 load operation reported an error    
4/29/2016 7:30:51 PM - current media D06674 complete, requesting next resource Any

I have seen this error with physical tape drives when needs cleaning or with bad media with error code 84 , but since the library is virtual should not be any cleaning issue. Any suggestion please....

Stop NBU -  check in

netbackup/db/media/tpreq

Are there any files, if yes, delete them.

Check there are no outstanding reservation:

nbrbutil -dump (Look in MDS section at bottom of output).
