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_2.
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.
The bptm logs shows :
