This RDAC handler is suggested in
and I had to download it from
http://www.lsi.com/rdac/rdac-LINUX-09.02.C5.16-source.tar.gz, and compile
it. I haven't tested the RDAC from the Kernel... Do you have any info on how
to do it?

What I have done previously was to test the DM-multipath with the
"path_checker readsector0" in /etc/multipath. I got the same problems in
this Raid 10 configuration for the DS3300. However, dividing the same DS3300
in 6 R1, I had no problems either with the present RDAC or with readsector0,
but I got better I/O performance with the RDAC.
