Thanks all who have given me response.
I don't want the second media server drive is written or controlled by
third media server.
I want to add another four drive in my existing Tape Library & want to
connect that new four tape drive to third media server.
One Tape library having one robot & eight drive, first four drive is
already connected with my existing media server( second media server) & I
want to add another four connect it to third media server.
Will it possible.
Thanks & regards

Sure it does... he just said they were SCSI connected to the 3rd Media

That's the key question. I read his note to say that they were connected
to the 2nd Media Server but he wants to write to them via the 3rd Media
Server. If I read it correctly, he can't do what he wants. If you read
it correctly, you're right and my answer was wrong.
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.

My Tape drive is directly conected to media server thru scsi cable.
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 have master server with Netbackup enterprise 6.0 running on solaris 8
& two media server having two HPESl 9300 series tape library with four
drive in each Library.
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.
