[dm-devel] DM, Multipath, and LSI Disk Arrays

[Chris Penney]

Hi,

I'm not sure if this is the right list so apologies in advance if I'm
in the wrong spot.  The search tool for this list doesn't seem to work
either.

I have an Intel system with dual Qlogic HBAs (2340s) that talk to an
STK D280 disk array (I see the generic multipath.conf lists a D280 as
a device in the config file).  I'm using SLES 9 SP1 w/ multipath-tools
0.3.6-0.3.

They way the system is setup, hba1 talks to the A controller of the
D280 and hba2 talks to the B controller (they are on seperate sans). 
The box has four luns, two are active on port A and two are active on
port B.  When I let multipath do it's thing it wants to use port B for
everything and that triggers a fail over of the A luns to port B.

If I do the dmsetup commands by hand I can get what I want, but is
there a way to do this automatically?  The thought of having a self
made hack init script to do this seems highly suspect.
