How to connect Master server with two shared robots in one library

The robot can be seen from system.

#cfgadm al

c4::500104f000affbb9           med-changer  connected    configured   unknown

I finished all steps to do sg build and install but sgcan still didn't show the robot even though I can see them under /dev/sg

root@dvifap13:/dev/sg # ls -l | grep bb9
lrwxrwxrwx   1 root     root          91 Dec  3 14:50 c0tw500104f000affbb9l0 -> ../../devices/pci@7c0/pci@0/pci@1/pci@0,2/fibre-channel@2/fp@0,0/sg@w500104f000affbb9,0:raw

I manually created the robot, but it shows not enabled. I used the device configuration Wizard, it didn't show the newly configured robot, all drives in that library shows standalone drives.Please let me know how to configure to make the master server be able to see the shared two robots in the same library.

Thanks!
