hradware_handler error on 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
Aug 12 13:48:33 cluster3 kernel: device-mapper: table: 253:19: multipath: unknown hardware handler type

If anyone can help, thanks in advance.

What made it neccessary to have an entry in multipath.conf? The built-in
values cover the settings for the old MSA1000.

Try "1 hp-sw" instead of "1 hp_sw".

The underscore got changed when the hp handler was submitted upstream.
