Robot not recognized
We have a master server with NBU 6.0 MP7 (master is acting as media server only). A few days back it got rebooted unexpectedly and after it came up the OS wasn't able to recognize the robot i.e. "IBM 03584L32 SCSI Changer Device" and the four drives i.e. "IBM ULT3580-TD4 SCSI Sequential Device" as seen from the device management console (refer attachment).
We have rebooted the server twice once before the reboot of the tape library and once after the reboot of the library and it is still the same. We also checked the hardware status of the device and found no faults.
NOTE: Another team is using the same library for running the backup jobs and didnt report any issues so we can consider the tape library is running fine.
It looks like the NBU software cannot see/connect to the tape library drives.
