My robotic arm is not functioning.What will happen in this case?
NBU will down all drives eventually and that's it
Library will not be down?
Without the autoloader (arm) how are you going to move the tapes from the slot to the drive and vice
versa. Once the arm is down the drives will be down and so will be your library.
So when library goes down,it means my arm is not functioning?
Not necessary. You need to verify this using tape library diagnostic tools, NBU just sends SCSI commands to control library, if it can't execute command NBU marks the resource as down. Why this happens is another question - related to driver/os/cables/zoning/tape/robot or even something else.
Another 'Lets Suppose' question?
