Good Morning --
Was there ever a resolution to your NB5.0MP2/LTO end of tape problem?
I'm currently fighting with a new installation NB5.1 on a Solaris 9 system using
LTO2 tape drives. My backups ALWAYS fail either at a checkpoint-restart WRITE
or
at the very last WRITE of the backup, regardless of how big the backup is.
I've been told by my NetBackup tech support (via Sun) that it was a hardware
configuration problem.
The backups always fail, regardless of any st.conf modifications and I've even
taken the fiber switch out of the mix. Here's a summary of my hardware and the
types of errors I'm seeing (by the way, ufsdump works just fine....).
Master: Solaris 9 version 4/04 on a Sun V240 with 2 LSI Logic FC919X HBAs
running
NB5.1 Enterprise Server. One LSI Logic HBA is connected directly to the
fiber/scsi
bridge of a Qualstar 88264 LTO2 library, the other to a Brocade 32-port fiber
switch attached to a Sun 3511 storage array.
I have tried at least 4 different st.conf LTO2 configurations with same failing
results and am now not using any special LTO2 definitions.
Here are the failure errors from both the NetBackup reports and from the bptm
logs:

Since ufsdump works, this is indicating a NetBackup 5.1 problem. Anyway, I
notice
in your post-November posts, you referred to NB4.5 servers. Did you have to
downgrade NetBackup in order to get your LTO drives to work properly?
