    Did it ever work If so, what changed

    Are you using enctryption of any type (MSEO / KMS / 3rd party)

    What is the SIZR_DATA_BUFFER setting (/usr/openv/netbackup/db/config/SIZE_DATA_BUFFERS)

    What is the os of the media server

    Typically, these issues are likely to have a cause outside of NBU, possible hardware fault, or driver/ firmware issue (or encryption isue).  NBU sends backup data in blocks (say 256k) to the OS, and the OS instructs the drive to write the data to tape using this block size.  What is happening, is that the backup fits in say 100 blocks (just keeping the numbers simple) but the tape drive write >100 blocks.

    That is outside of our control.

    OK, the block size is fine, I'd suggest looking at drivers  and firmware in that case.

      I agree with mph999 
      This error: check tape/driver block size configuration refers to the Solaris st driver.
      The NBU buffer size is not the same thing. 

      You may also want to read through the Solaris chapter of the Device Configuration Guide (there is a .txt version in /usr/openv/volmgr if I remember correctly). 

      PS: 
      Any reason why you installed such an old NBU version? (This is not the reason for the error, I'm just wondering)
