I tried adding/removing new storage on sles10. It took few minutes to find the new target devices (the new target message was showed on /var/log/messages) then took few minutes to add the path. I did not run multipath again. The srp_daemon.sh scanned the new target and added path automatically.

I guess leave 91-srp.rules in for now, it seems benign.
