[dm-devel] hardware_handler error with HP MSA1000



Hi
I have been strugling with an HP MSA1000 for a few weeks now.
I am using the old active/passive firmware.
Here is the device section of my multipath.conf :

devices {
device {
vendor "COMPAQ"
product "MSA1000"
hardware_handler "1 hp_sw"
path_grouping_policy group_by_prio
path_checker hp_sw

}
}

I am under RHEL5.2 and this is the rpm package of dm-multipath 0.4.7-16.el5.
Here is my /var/log/messages when i start multipathd daemon :
Aug 12 13:48:33 cluster3 kernel: device-mapper: ioctl: error adding target to table

If anyone can help, thanks in advance.
