About choosing a tape driver on AIX
If you use IBM tape drives, Veritas recommends that you install the IBM AIX Atape driver. For information about the driver, see the IBM documentation.
If you use other tape drives, Veritas recommends that you use the IBM AIX ost (other SCSI tape) driver. For information about the driver, see the IBM documentation.
For information about the drivers and how to configure device files, see the IBM documentation.
