> HP Ultrium documentation says two drivers should be automatically up,
> sym53c8xx for LSI SCSI interface "st" for tape and /proc/scsi/scsi
> should contain information about tape drive, e.g. SCSI ID. However
> none of them happened in my case! (document: "UP LTO Ultrium 2-3 -
> Unix Config Guide")

> The SCSI adapter is an LSI53C1030. The system has another the same
> adapter which is used for hard disk drives.

> The interesting part is, the hard disk are detected and even OS boots
