Infrastructure Software

I have the following firewire hardware;
2 Adaptec 1394/Firewire 3-port Card Kit
1 ADS Pyro FireWire 1394 External Drive Kit
with 40Gb Maxtor inside.

I have installed Red Hat 2.1AS 2.4.9-e.3 installed on two pc's and have installed the Oracle firewire drivers/kernel--the kernel I am running is "Linux k1 2.4.20-rc2-orafw #1 Thu Nov 21 16:14:19 PST 2002 i686 unknown".

After rebooting both machines, I load the following modules manaually:

1. modprobe ohci1394
2. modprobe sd_mod
3. modprobe sbp2 sbp2_exclusive_login=0

The lsmod returns the following (for both machines);
[root@k1 firewire]# lsmod
Module Size Used by Not tainted
sbp2 18528 0
sd_mod 11820 0 (unused)
scsi_mod 99308 2 [sbp2 sd_mod]
ohci1394 17640 0 (unused)
ieee1394 43820 0 [sbp2 ohci1394]
autofs 10804 0 (autoclean) (unused)

Now here is my problem, if it is a problem. When I run
therescan-scsi-bus.sh script from one machine I get:

[root@k1 firewire]# ./rescan-scsi-bus.sh
Host adapter 0 (sbp2) found.
Scanning for device 0 0 0 0 ...
OLD: Host: scsi0 Channel: 00 Id: 00 Lun: 00

0 new device(s) found.
0 device(s) removed.
[root@k1 firewire]#

While on the other machine I get:

[root@k2 firewire]# ./rescan-scsi-bus.sh
Host adapter 0 (sbp2) found.
0 new device(s) found.
0 device(s) removed.
[root@k2 firewire]#

Note that on the second machine (k2) I don't see my Firewire hard disk.

My question is, is this a problem--maybe my ADS firewire enclosure doesn't do concurrent firewire access? Or am I jumping to conclusions?

Thanks for any help
