3580 drive unknown

I have a newly installed TSM v5.1.1.6 on W2K and library IBM 3583 where 2 of
the drives are in state unknown. I´m not sure if it has been like this from
the beginning, but does anybody know how I can get them working again? The 2
drives are on a separate Adaptec 29160, and the library and working drive on
another Adaptec 29160. An update won´t do it, and W2K think that the drives
works okey! I have deleted them and defined them again. I have changed SCSI
cables to!!

Thanks in advance!
