Ah... 84 media write errors, I remember them well.  All the other responses are 
spot on, though we received scads of 84 media write errors because of a FC/SCSI 
bridge buffer problem.  As far as Veritas is concerned, they told us at the 
time that 84s indicated any type of disconnect/drive/media error beyond NB.  
Let me know if you need any more info, but check your SCSI path too.

        We had a problem this weekend with the file system that the database 
was on
        filling up.  The server NB master server also panic'ed causing many 
backups
        to fail.  Now when I am trying to perform backups, I am getting random
        errors of "84 media write error".  I have attempted to, and still 
attempting
        to, talk to Veritas support but I thought I would throw this out to see 
if
        anyone in the group has had this before.
        
        The environment is NB 3.41 Datacenter Patched to level 6.  It runs SSO 
with
        5 media servers and 1 master media.  The servers are solaris 8.
        
        Veritas is stumped it seems and it has been like this for a couple 
days. 
        
        Any help you can provide would be awesome.
        
        Thanks,
        Mike
