For unknown tapes, the std proceedure is to make your own with an 
amanda utility called 'tapetype' for some strange reason. ;-)

2 things to consider, one being that if this drive has any hardware 
compression, it should be turned off permanently as amanda can use 
compressors that compress far better than the RLL in the average 
drive can.  The second reason is that tapetype feeds the tape with 
the output of /dev/urandom, which as totally uncompressible and in 
fact may cause the data on tape to grow considerably.  Amanda wants 
to know what the tape holds and she will total it up *after* 
applying any compression specified in the dumptype

The 2nd item is a time warning, fire up tapetype and go home for the 
night.  It *might* be done in the morning, but on a 100Tb tape its 
going to take quite a while unless that drive can move 
multimegabytes a second...

Clip what it outputs on the screen and paste it into your tapetype 
definition in amanda.conf, and post it here so someone can add it 
to the example amanda.conf in the archive.
