Now that RHEL 5.4 is out with md3000i support in scsi_dh_rdac, is there an updated set of instructions for configuring multipath for an md3000i connected to a RHEL5.4 box?

However, I've been testing some newer versions of the kernel which do have MD3000i support. I've only installed the latest version today so I haven't had time to do much testing yet, but it does look promising. The kernels are available here: http://people.redhat.com/dzickus/el5/ Could you post the output of config and path output?
