Thanks to all who replied. Here are the various replies:

a BA-353 automatically "terminates" my SCSI bus. I read that an
unterminated SCSI bus could break havoc on my disks.

=======================
1) Most respondents told me to run doconfig in order to have the device
listed in the boot messages.
2) The TLZ06 is compatible with the TLZ07, but I should not use 120m
cartdridges in the TLZ06
as they are thinner and can jam in the unit.
3) I should have used SCSI ID 5 for the tape intead of six, but that does
not matter.
4) No one could confirm that the BA353 terminates the bus.
Thanks again
P.S.: I decided to back up the machine on a remot server with rdump because
I fear a termination problem and someone told me that it could lead to data
corruption !
