Ultrium 5 Tape Blade seen as cd-rom

[Ulf Zimmermann]

We have a SB3000c Ultrium-5 Tape Blade. It comes with a SmartArray P212 controller. After "echo 'engage scsi' /proc/driver/cciss/cciss0" it only shows up as CD-Rom:

scsi2 : cciss
Vendor: HP Model: Ultrium 5-SCSI Rev: Z38D
Type: CD-ROM ANSI SCSI revision: 06
scsi 2:0:0:0: Attached scsi generic sg0 type 5
sr0: scsi-1 drive
Uniform CD-ROM driver Revision: 3.20
sr 2:0:0:0: Attached scsi CD-ROM sr0

Doesn't matter if the kernel module for st or osst is loaded first or later via modprobe. lsscsi also shows it as cdrom:

ns03new root /home/ulf # lsscsi
[2:0:0:0] cd/dvd HP Ultrium 5-SCSI Z38D /dev/scd0

The documentation from HP for this product is really abysmal.
