I've also seen that you should check and experiment with the
CLIENT=5FREAD=5FTIMEOUT parm if you're backing up many large files.

Perhaps you've solved your problem by now, but I was receiving 84 errors=

on our LTO drives that could not be isolated.  Veritas indicated that an=

84 error meaning that communication with the drive was interrupted in
some way, and that it happened below the application level.  After
trying various firmware upgrades on drives, HBAs, and FC/SCSI bridges,
we finally swapped out our Brocade switch and the problem went away.
For your situation it could be any link in your FC path.  I would be
interested to know what you find.

I have sometimes a failed backup with error 84. It occurs after NBU have=

done a lot of work in this class (more than 500GB). So, I don't suspect
drive error, drive configuration errors, or media type errors, like
Troubleshoot
Guide suggests. The medias are all new, and the drive is clean. This
class
use a storage unit with two drives.
My master server is a Solaris8, Netbackup 3.4 with patch 34=5F2.
The media server, where the error occurs, is a Tru64 5.1 with the same
patch
level. The tape drive is a 9840FC. In this media server are another
backups
running pretty well.
