1. make sure all services are running.
2.  try deleting devices drive/robot from the GUi.  If it fails you can use 
vmglob -delete xxx from a command line.

Once the devices are removed.

3. Run scan or sgscan in /volmgr/bin
      You should see a robot and x number of drives.

     Note: if you don't see devices call the system administrator to check the 
storage/San presentation for the devices.

4. Once the O/S can see the devices run tpautoconf from volmgr/bin

You should have drives and robot again.
