Subject: [NTLUG:Discuss] Firewire and RH9

I am trying to use an external firewire hard drive
with RH9 and am having some difficulty.  I can see in
dmesg where it sees the Maxtor drive but it never
assigns it a device such as sda or sdb. 

What am I missing?

Thanks

David

BTW Kernel 2.4.20-20.9

Dave,

Your posting prompted me to attempt to attach a firewire drive I had
hanging around to my linux box.  It was successful.

I am using a LaCie firewire drive, which is actually a seagate drive in
a nice box.

The steps listed below assume that you don't currently have a scsi
device installed on your box.

If you do an <lsmod>, you need to make sure you have the following
modules:

ohci1394               20136   0  (unused)
ieee1394               48748   0  [sbp2 ohci1394]
sbp2
sd_mod                 13452   2
scsi_mod              107512   3  [sbp2 dpt_i2o sd_mod]

My install is a stock redhat 9.0 install.  My kernel is 2.4.20-19.9.  I
had my firewire controller installed before I loaded linux.

If you don't have these modules listed, then you will have to add them to
your
kernel.  Unfortunately I have only used <rpm> for most of my installs,
and don't feel comfortable walking anyone through any kernel
modifications.

If you do a <cat /proc/scsi/scsi> and find nothing, then you need to run
the rescan-scsi-bus.sh script that can be downloaded from
http://www.linux1394.org/sbp2.html.

After you run the script, try to run <cat /proc/scsi/scsi> again.  If
things worked out right, then you should see some data in the output,
similar to this:

Host: scsi1 Channel: 00 Id: 00 Lun: 00
  Vendor: ST316002 Model: 1A               Rev: 3.06
  Type:   Direct-Access                    ANSI SCSI revision: 06

At this point, you should be able to do an <fdisk /dev/sda> and play the
partition game however you want to.  After <fdisk>, run <mkfs.ext3> to
write the filesystem on whichever partition/partitions you wish.  I just
used one
partition, so my <df -h> for the firewire drive looks like this:

/dev/sda              147G  1.8G  138G   2% /firewire_1

I tried to enter this drive in /etc/fstab, but it didn't work.  I found
out that you have to run the <rescan-scsi-bus.sh> script and <mount>
command every time you reboot.  To get around this, I edited the
/etc/rc.d/rc.local file to run those 2 commands during bootup.

Hope this helps you out.

Good luck, and as always, YMMV.
