Linux aic7xxx driver doesn't see my tape drive

Linux aic7xxx driver doesn't see my tape drive

[Kevin J. Cummings]

Can someone please explain why my Adaptec 2940U Ultra Wide SCSI 
controller (AutoSCSI in the controller BIOS) shows me that my Archive 
Python DAT tape drive is on Channel 0, id 3, but when I boot RedHat's 
linux-2.4.20-28.9, the aic7xxx module only sees my disk drive on channel 
0, id 6?  Yes, both devices are plugged into the narrow bus, and auto 
termination is configured on the controller, and the devices are in the 
same order as before (see below).

This used to work fine on my BusLogic BT-948 controller [which I had to 
stop using on my new motherboard (because the ABIT AF7 motherboard won't 
finish POST with the BusLogic BT-948 controller plugged into a PCI 
slot.....)]

Please post the output of lspci.

Re: Linux aic7xxx driver doesn't see my tape drive

[Kevin J. Cummings]

Well,
	Given that the tape drive is attached to the Adaptec 2940U SCSI 
controller, doesn't st have to eventually send SCSI commands to the 
aic7xxx driver????

	Here are the relevent modules after I:

depmod -ae
modprobe st

> [root@kjc386 root]# lsmod
> st                     29964   0  (unused)

> scsi_mod              102968   6  [st sg sr_mod ide-scsi aic7xxx sd_mod]

But, there is still no mention of the tape drive in /proc/scsi/scsi, nor 
when I:

cdrecord --scanbus

Is this also reflected on the bios output during post on the scsci 
controller?  Sorry if you already mentioned in a previous, but errantly 
deleted them.

Well that's not good! Mine does show up:

When you boot the system, during the Adaptec startup, there can be, if 
it's turned on, a Control-A prompt.  Does the tape drive show up in the 
bios setup screens?

Yes, it does.  Tape drive is id 3, disk drive is id 6....

No, during POST, I can see both devices as id 3 (tape drive) and id 6 
(disk drive) before linux boots.  I can see both devices using the 
Auto-SCSI in the SCSI BIOS if I invoke it (it even tells me that the 
tape drive is not a disk drive!)....

I don't know if the st driver actually requires this, but the standard is
for your first tape to be on ID 6.  I'm, in fact, using a 2940U with a
Python DAT on ID 6 with 2.4.25 on a PC next to me right now.

Since you're working with a tape drive, I'll take this chance to advertise
for bacula:  http://www.bacula.org
A free network backup solution. ;)

Other investigatory things you should look at are 'dmesg'
'cat /proc/scsi/scsi' and 'cat /proc/scsi/(modulename)/*'

Digging around in st.c and scsi_scan.c don't indicate anything strange, but,
hey, try out ID 6 anyway -- this is the first time I've looked at either of
those files!

But that's where my disk drive is.   B^)  Besides.  This setup worked 
just fine when the SCSI controller was a BusLogic BT-948....  That's 
what makes me think its an aic7xxx driver problem....

The tape drive isn't found anyplace there.

I suppose I could swap the Tape and Disk drive IDs, when I get the 
chance to....

Very odd indeed.  And I would suggest putting the devices on the chain one 
at a time if possible and see what happens when you boot.

Re: Linux aic7xxx driver doesn't see my tape drive

[Kevin J. Cummings]

Well, I finally upgraded to Fedora Core 2 yesterday.  Surprise!  I can 
now see my tape drive again....  Nothing has changed as far as I can 
tell hardware-wise, in fact, I haven't even powered the system off....

Oh well.  Chaulk another one up to development software....

Thanks to everyone who offered help!
