T090 - Invalid Cleaning Tape
Description GUI Description: A non-cleaning tape cartridge was used to attempt to clean 
the tape drive.
Explanation: System determines that the tape cartridge used to clean a drive 
is not a cleaning tape. This RAS ticket differs from the TapeAlert 23 RAS 
ticket (T048
) in that this RAS ticket will be generated any time a non-cleaning 
tape is used to clean a drive, not just in the case where the drive requires 
cleaning and posts a TapeAlert 23.
Detection Scenarios After loading a tape cartridge to clean a drive, the system notices that 
cleaning has not begun within 30 seconds.
Root Causes • User or library attempts to mount a cleaning tape cartridge, but the tape is 
not actually a cleaning tape.
• User mistakenly loads a data tape cartridge as a cleaning tape.
• An inventory or application issue results in a data tape cartridge being 
loaded when the drive expects a cleaning tape.
