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

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

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.
