NetVault on Solaris 11

Hello,

Does anyone here have any experience with NetVault on Solaris 11?

We are current running version 8.1 on Solaris 10 which has worked well 
for us.  We recently tried the client on Solaris 11 (Express, latest 
SRU) and the client refused to cooperate (it returned waiting for media 
errors).  We were able to backup the machine from a Solaris 10 zone on 
the same box.

I'm unsure whether we have a Solaris or NetVault problem.  We haven't  
tried the latest client version, that world require an upgrade to the 
server.  The last time the admin of that box tried an upgrade, he had 
problems had to revert back to 8.1.

Thanks for your time.
