scsi_dh_rdac modules is insmodded by multipath when multipathd is

So, it is effective when multipath starts.
If it is effective, I don't need to patch it... Thank you very much.
You were saying that you could provide some debugging code if I'm
interested? Well it seems that I don't have a choice... So please do
so :)
Basically I want to find out if we are getting and sense codes that we
are not handling. To that effect, andd the following line at the top of
the function rdac_check_sense()
--------
sdev_printk(KERN_ERR, sdev, "I/O returned with sense %02x/%02x/%02x",
sense_hdr->sense_key, sense_hdr->asc, sense_hdr->ascq);
---------
compile the module, run your tests and get me /var/log/messages.
Might this be the same issue as you worked through with Babu last October?
