Default Problem detecting HP Tape Drive

You may look into stinit (man stinit).

Subject: Problem detecting HP Tape Drive

Hello

I do have problem using Linux with an external HP tape drive. The
server platform is also an HP Server; the server is an HP ML350 G4,
and the Tape drive is a HP Storage Works Ultrium 448 - 1U Rack-
mountable.

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
from them, but I can't make the tape drive work. Moreover, in system
boot up, LSI SCSI BIOS displays information saying there is a tape
drive connected!

Any one has same experience, suggestion, comments or clues?

I've place a zip file here:
http://msarmadi.googlepages.com/report_files.zip
which contains:

- dmesg
- lshal
- lsmod
- lspci -vv
- cat /proc/scsi/scsi > proc.scsi.scsi
- cat /proc/modules > proc.modules
- uname -a > uname

Also, below there are detailed information about devices and OS config/
log files.

I don't see the st kernel module listed in lsmod. Try "modprobe st" to load it.

Why is your /proc/scsi/scsi output empty?
I'd expect to see something like this:

Default Problem detecting HP Tape Drive

I did, also tried loading st module manually.
modprobe sym53c8xx

but /proc/scsi/scsi is still empty

modprobe st

and in messages just mention the st module with a certain offset is
loaded, nothing about the tape detection then also tried "mt" utility
to send some commands to the tape, but nothing works!??!?!

Default Problem detecting HP Tape Drive

Hey there,
I have a DAT72 tape drive that wasnt accessible, even tho the system said it
was there (in /proc/scsi/scsi) ...here's what i do to make it
visible/useable...:

for x in /proc/driver/cciss/cciss0
do
echo "engage scsi" > $x
done

After running the script, the tape is visible and works.

Cheers,

Phil

I really don't know why that would be. /proc/scsi/scsi is part of the /proc pseudo
filesystem. The fact that that "file" is empty indicates to me that there's something
fairly fundamentally wrong with your SCSI driver setup.

Does this happen when the system is newly booted? Does the same happen if the tape drives
are disconnected from the SCSI bus?

Solved!

The answer is:

echo "engage scsi" > /proc/drivers/cciss/cciss1

With that thing everything worked fine.

Yes, It does.

Yes, but boot messages(before OS boot up) are not shown on the screen
obviously. I have no
