Hi,

We're running NBU 6.0 MP5 on Solaris. I have a question relating to the backup 
network.

We had an issue recently where we're having problems with our tape drives 
suddenly going AVR after we had a comms issue. We're still trying to resolve 
this but it looks like there's a config problem on the media servers...they 
think that the drives which are on one robot are in fact on another. TPCONFIG 
shows it how it how it should be but somewhere else there's some sort of 
mis-match.

Anyway, because of this we had to run our duplications across site over what we 
thought was the backup network which in fact was our main network. All along 
the route we had selected the BN media server hostname interfaces but somehow 
it had gone off of that. 

Is it possible that if in the bp.conf as well as having the hostname-BN 
interface you also have listed the server hostname (without the BN interface), 
that if it finds the route extremely busy that it will jump off of it and go 
down the main network?

I thought that i heard somewhere that you shouldn't have your main network 
connection listed in the bp.conf if you have a dedicated backup network....

Any thoughts and advice greatly welcome as this caused us a sev 2!!!

Thanks,
Chris
