  Tim mentions a couple of possibilities for how to get the drives cleaned.
Here are a couple of others.  After you get the tape properly added to Media
Manager (the media manager display shows the tape as a DLT cleaning tape),
you can clean by library, frequency, manually (as Tim described), or
possibly by TapeAlert.  Library-based cleaning should only clean when the
drive indicates it is dirty, but does not alert NBU when the cleaner needs
to be changed. Frequency-based cleaning is integrated into NBU (an option on
either the drive settings or on the cleaning tape - I forget), but may
result in over-cleaning, shortening drive lifespan.  Manual cleaning is,
well, manual.  TapeAlert, if the library and drive support it, is integrated
into NBU, and will only clean the drives when needed.

My guess is that your library is configured to "hide" slot 20 and only 
use it internally.  Is your library setup to perform the cleaning?  If 
so, you can do one of two things.  You can either let the library 
perform the cleanings or disable library based cleaning and allow 
NetBackup to perform the cleaning.

Once you disable the library based tape cleaning, you can define the 
cleaning tape to NBU.  You can do this in any number of ways, the most 
common way is to use a barcode label that starts with CLN, define a 
barcode rule so that any tape which starts with CLN will become a 
cleaning tape and be placed in the NONE pool and then finally, perform 
a robot inventory.  Once you've got the tape defined, you can then 
issue the tpclean -C command as you mentioned.  You can also right 
click on the drive in the GUI and choose cleaning from there.

Hope that helps and good luck.
