devices in OST failover

Hi all!

I'm going to set up an active/active OST failover, but gets a litle
confused. In the manual in section 6.4.2 it says:

"To expand the simple two-node example, we add ost2 which is primary on
nodeB, and is on the LUNs nodeB:/dev/sdc1 and nodeA:/dev/sdd1. This is
to demonstrate the /dev/ identify can differ between nodes, but both
devices must map to the same physical LUN." Is this the same disc in a
SAN?

I want to have a local /dev/sdaX on each OST - with same size. That
means:

ost1 with its own /dev/sda3
                             in an active/active failover with
ost2 with its own /dev/sda3

Is this possible, or have I misunderstanded something?
