To clarify my question:

I currently have a live NetBackup environment where the master server
is a Dell 2950 and I have two media servers that are solaris boxes
running RHEL 4. My department wants to decommission the older boxes
and move NetBackup to newer boxes, and I wanted to upgrade to 7.0
anyway, so I decided to kill two birds with one stone and build 1 new
master and 2 new media, install NBU 7 on the new environment and then
zone my existing libraries into the new environment and then point all
the servers I'm backing up to the new environment.

On my live NetBackup environment (the RHEL4 one), when I go into the
NBU hardware configuration wizard and scan for devices, the wizard
comes back and says it sees 3 libraries and 92 drives (which is the
number I expect to see). When I shut down my live environment and
bring up the NBU 7 environment and run the hardware wizard, it sees
like 16 robots and 400 drives. I'm trying to figure out why my NBU
6.0/RHEL4 environment is able to see one device file per robot/tape
drive, but my NBU 7/RHEL5 environment thinks each path is 1 device.
I'm not sure where to begin researching this issue. I'm in the process
of skimming through the NBU 7 device configuration manual, the HBA
documentation and Red Hat's storage documentation.

Any light that can be shed on this will be greatly appreciated.
