I have not worked with Exabyte tape drives but I think the define drive
statement you have above is incorrect.  First, you did not define a
library for it (yes, even stand-alone drive requires a library), second,
the device definition should be mt0, and not rmt0.

To define the library.

adsm>  define library library_name libtype=manual

After you have defined the library, define the drive.

adsm> define drive library_name tapedrive_name device=/dev/mt0
