Hi Christophe, Thank you for the prompt reply.
I'm able to load the lpfc driver from the initrd image. looking into mkinitrd script i didn't found any variables called 'deoped'. do you mean using the mkinitrd to call the '/sbin/multipathd'? i tried to add /sbin/multipathd, i would say i may keyed in the wrong one.Have you tried to get inspiration from the mkinitrd scripts in deoped in multipath/. These are Debian orientated, but you should be able to adapt them to FC.
Any other-way? hope to hear from you soon. Thanks. Regards, hwahing
