dm-multipath use
Are folks in the Centos community succesfully using device-mapper-multipath?
I am looking to deploy it for error handling on our iSCSI setup but there
seems to be little traffic about this package on the Centos forums, as far
as I can tell, and there seems to be a number of small issues based on my
reading the dm-multipath developer lists and related resources.

Multipathing with Sun 7310
Dear list,
we have a relatively new Sun Storage 7310, where we connect CentOS 5.5
Servers (IBM LS21/LS41 Blades) via Brocade Switches, 4GBit FC. The Blades
boot from SAN via qla2xxx, and have no harddisks at all. We want them to
use multipathing from the very beginning, so /boot and / are already seen
by multipathd. Problem is, that the Sun 7310 has two storage heads which
run in
