SOLUTION
 Make sure you are using data and cleaning tapes that are
compatible with the drive and model of your library.
The library automatically unloads incompatible tapes, the <Media
Attention> LED flashes, and an exclamation mark (!) is displayed in
the inventory display for the indicated slot number.
 Export the media in order to clear the state.
 Make sure that the tape is write enabled (move the write-protect
switch to the enabled position).
 Make sure you have the appropriate data tape for your library
model.
 Make sure you are using an Ultrium tape that has not been
degaussed. Do not degauss Ultrium tapes.
 Make sure that the tape has not been exposed to harsh
environmental or electrical conditions and is not physically
damaged in any way.
 Many backup applications do not read or write to tapes that were
created using a different backup application. In this case, perform
an erase, format, or label operation on the tape.
 Make sure you understand any data protection or overwrite
protection schemes that your backup application may be using,
which could prevent you from writing to a given tape.
 Retry the operation with a different, known good tape.
Clean the tape drive using:

- OCP, see Section 3.1.7
- RMU, see Section 3.2.9.6
 Check all power cord connections.
 Make sure the power switch on the front panel is in the <ON>
position.
 Make sure there is power to the outlet. Try another working outlet.
 Replace the power cord.
 Contact your service representative.
 Make sure the power cord is connected.
 Make sure the power switch is on.
 Power cycle the library.
 Download the library firmware.
 Contact your service representative.
