Guys running Netbackup 5.0Mp7 on solaris 9 environment.

I have a master server connected to L700 via fibre through a SANBOX2
switch to robot and 6 drives.

The master server has 2 HBA's ( as i believe Sun impose a limit of 3 *
LTO2 drives per 2GB HBA ).

I have 2 SAN Media servers ( DB nodes ) each connected via the switch to
the first 3 drives which are shared.

I am adding 2 extra drives and another SAN Media server.

Question is :-

Using robtest i will see the extra drives in the L700 once added but i
cant add these drives to the Master server as i have already hit my
limit of drives / HBA. The new media server will be connected through
the switch to the 2 new drives and will have the devices set up. The
query i have is how does the master server ( which is the robot
controller ) able to put the tapes into the drives for use with the 3rd
Media server? As i wont have the devices and thus /dev/sg paths set up
for these new drives on the master. Im unclear as to how this will work.

Anyone any ideas? I cant see anything in the docs from the scan through
i have had
