Below is the config I am using now on one of my Ubuntu Server machines with an MD3000i.. With this config, the i/o errors usually show up for a little bit until rdac disables the necessary paths, and then they go away. Failover works *okay* with this configuration.. if anyone on the list has more experience with this sort of thing, feedback or recommendations on how to improve this config are welcome. Hope this helps..
features "1 queue_if_no_path"
prio_callout "/sbin/mpath_prio_rdac /dev/%n"
hardware_handler "1 rdac"
# prio "rdac"
# Additional wwid-to-alias mappings here..

Subject: MD3000 on Debian Lenny
I'm trying to get a MD3000 working with Debian Lenny and it looks like a
big mess from my POV. Dell only supports SuSE and RedHat, but I didn't
expect that it'd be so hard to get this up and running on Debian.
Can anyone give me some pointers to get this working? I don't care if I
can use multipath or not. I just want a reliable way to access the disks.
So far I've tryed with the multipath-tools, dm-rdac and porting (kind of)
the dell SM-Tools to Debian, but nothing got me rid of the "I/O errors"
that happen when accessing the exported devices.
