It should "just work" without installing any special drivers.  Is your 
machine seeing the FC card ok?

You should see something like this in dmesg:

[1224872.272299] qla2xxx 0000:02:08.0: LOOP UP detected (2 Gbps).
[1224873.049784] scsi 14:0:0:0: Sequential-Access IBM      ULTRIUM-TD2

[1224873.061441] st 14:0:0:0: Attached scsi generic sg3 type 1
[1224873.061919] st 14:0:1:0: Attached scsi tape st1
[1224873.062048] st 14:0:1:0: st1: try direct i/o: yes (alignment 4 B)
[1224873.062244] st 14:0:1:0: Attached scsi generic sg4 type 1

Do you see anything like that?  The first couple lines indicate that you 
can talk to the drive over the fc loop, the "st0" and "st1" lines will 
show up if the st driver is loaded properly.

If you don't see something like the first few lines, then your machine 
isn't seeing the tape drive over the fiberchannel connection.
