As you actually get TapeAlterts regarding the SCSI interfaces, I would
recommend trying a different cable and terminator anyway.
As I don't recall which tape hardware you're using, it might also be
worth checking if, from the libraries control panel, you can disable
an - unused - secondary SCSI interface.

Looks good, i.e. the SCSI hardware negotiated the correct transfer
settings.

That is an HBA I don't have access to. But the LSI controllers and
drivers have a reputation of reliability and very good linux support.
One thing to consider is that using a RAID HBA for tape drives often
doesn't work very well. As I don't know if your HBA does include
internal RAID functions, you should verify that first.
If you find you're using a RAID-enabled HBA, it might be worthwile
trying a different, simpler HBA. Alternatively, you could try to
explicitly disable the RAID functionality - I *believe* this is
possible with the LSI FusionMPT compatible HBAs.

I don't think so.
