L180 drive error

[markton]

We got total 5 LTO2 drives in L180. We replaced two drives because of the error. But now, those two drives are not showing, showing the status is error. Robtest is showing the drives but sending a sense code error. What should I do?

Seems like the drives are different from the device you are using or you can say it is a stand alone type of drive. The error message you are receiving means the drive doesn't support your device. Are you using IBM and other all the drives has the same firmware? You can change the drives which is suitable for your device or use the same firmware for all the drives including the error ones.
