Well check FC cable 'polarity' - could be that you will have to swap on one end the TX and RX lines. Try this out.
Once drive will be connected that port should be online and will show you wwpn. After running scan you will have to perform NBU device configuration - wizard - to create tape drive and the changer special devices. Make sure that the drive you are connecting to is having a changer LUN on it, so the tape library will also appear out there.
Direct connection and via switch - both are supported - and tested - I am having both configs.
Hello, just an update. After a lot of troubleshooting and multiple support cases, it turned out that the tape library chassis was faulty (not the drive). Once we replaced it, and directly connected it to the appliance with the fiber cables (keeping in mind the right polarity), everything worked properly.
Have a nice day:)
