tape library configuration

Hi All

I have to configure tape library quantum i80 and its tape drives on our master server.

Master server Sun SOlaris 10  NBU 7.1.0.2

Tape library Quantum I80.

we have zoned all tape drives on master server, which is acting as media server.

tape drives are visible in output of cfgadm -al and in directory /dev/rmt I can see new *cbn files created.

But I am unable to find the robot and tape drives in output of following commands:

tpautoconf -r

tpautoconf -t

tpconfig -d

sgscan tape
sgscan changer

Please suggest on this also, please suggest if robot is also required to zone on this server.
