Based on the problem I just experienced, and taking into consideration I'm
a unix guy, not a windows guy, is there a "proper" way to get the windows
server, running windows 2003 server, to be able to use 3 of my drives from
the unix side without it causing havoc on my side ?

The windows server is a Dell Poweredge 1650 with a JNI 6410 PCI HBA
attached to the SAN. It's running NBU 4.5 FP6 and has an SSO license
installed.

We've zoned a single drive that only the windows server can see and use.
It was when I expanded the drives on the zone for the windows server when
problems on the unix nbu environment occured. It appeared like the windows
server was trying to communicate/use the shared tape drives even though
they has not been allocated to any storage unit on the windows nbu config.

I'd like to make this SSO setup work because the single tape device on the
windows box will cause some problems in the event that both a restore and
a backup are required at the same time.

Thanks.
