We are experiencing a problem when restoring an offline Oracle backup.  The EBU 
restore is failing with messages EBU-507 when trying to write a 3.5GB raw 
device.
The session text is below:

Beginning restore of file "/dev/rmpbosum"
    size 3500M bytes from tape file "242902441596"
  Reading backup file set "242902441596"

Any assistance would be appreciated.

TIA,
