Sure it does... he just said they were SCSI connected to

We need to know *which* media server those 4 new drives are physically connected to.
So that being said, he would need to create a
third robot instance which is defined as a remote robot and it would have
the drives indexed as follows:
TLD(2): Remotely Controlled by Media Server
#2:
Library Drive Index 1: Media Server 3 - Drive
#1
Library Drive Index 2: Media Server 3 - Drive
#2
Library Drive Index 3: Media Server 3 - Drive
#3
Library Drive Index 4: Media Server 3 - Drive
#4
So
when NetBackup executes a job requiring usage of Media Server #3, it knows the
robot is controlled by media server #2 and that the drives are
controlled by media server #3. This robot can then be added to Storage Unit
groups or policies, etc....

Well, why
can't he set something up like this:
Media
Server #1: Library Control + 4 Drives
Media
Server #2: Library Control + 4 Drives
Media
Server #3: 4 Drives with Media Server #2 being the remote host controlling the
library
You
don't need anything special to do this (such as the SSO). Matter of fact, the
Veritas Class I just got done taking has this exact setup (Quantum M1500
library with two drives, each drive controlled by a UNIX server with one of
the servers being the robot control host) and we didn't have anything special
beyond the base NetBackup
installation.
Media Server #3 has no physical access to the DRIVES that Media Server
#2 sees. Sure, NetBackup can tell MS # 2 to mount a tape, but MS # 3 has
no path to the actual tape devices. This goes beyond the "robot control
host" functionality.

There's not much hope of a different media server being able to write
to these tape drives. If you want a system to share tape drives, you
need some sort of physical connection between the media server and the tape
drives.
If you have a SAN but don't have your tape drives SAN
connected, you could consider a fibre to SCSI bridge and share those tape
drives. If you don't have a SAN at all, the costs probably aren't
justified.

We
want to add now four drive in our our existing Library & connect it to
third media server.
Please let me know is that possible.
Will this 3rd media server have direct access to
the tape drives? In other words, are the tape drives SAN-connected or
are they SCSI connected to the existing media servers?
If the tape
drives are SAN-connected, then what you want to do is fairly
straight-forward. You need to purchase the Shared Storage Option
licenses and then you would configure the tape drives to use the right robot
control hosts. You can dedicate tape drives to media servers - one way
to do this is to use SAN zoning.
