[Firewire-users] Device logon fail - exclusive use?

[Billy Verreynne (JW)]

o/s: RHEL4 (Nahant Update 5)
kernel: 2.6.9-55.0.6.ELsmp
drive: Lacie D2 (500GB/2 logons)

I've compiled and build the firewire source into a RPM and installed it.

The two platforms are mirror image (actually physical mirrors - I
installed one, broke its mirror and used that mirror for the 2nd
platform's root disk, only changing the hostname/IP).

Problem:
Despite the firewire driver seeing 2 logons, it seems that the 1st
platform grabs exclusive use of the firewire drive, not allowing the 2nd
platform access.

/etc/modprobe.conf contains:
options sbp2 exclusive_login=0

This is what /var/log/messages say on one:

This seems fine.. an initial logon error, but the retry worked and it
logged on.

The other platform's message log says:
==
Nov  5 15:46:10 ncas-poc1 kernel: sbp2: $Rev: 1265 $ Ben Collins
<bcollins at debian.org>
Nov  5 15:46:10 ncas-poc1 kernel: ieee1394: sbp2: Error querying logins
to SBP-2 device - timed out
Nov  5 15:46:10 ncas-poc1 kernel: ieee1394: sbp2: Device does not
support any more concurrent logins
Nov  5 15:46:10 ncas-poc1 kernel: sbp2: probe of 00d04b720507e42f-0
failed with error -16
==

So it seems that the 1st one grabbed exclusive use? (despite what
modprobe says)

I've googled and failed to turned up anything useful, except that
modeprobe.conf setting that does not seem to do it?

The usual non-void pointers, URLs, speculation, advice and comments will
be appreciated.. any beers can be forwarded to Cape Town.. :-)

Thanks.
