What's your SAN? Why don't you configure your raid1 on the SAN and let it publish that raid group as 1 LUN? Are you using a any kind of fibre switch between your cards and your SAN?

Subject: lpfc RAID1 device panics when one device goes away
I'm running RedHat AS 3.0 kernel 2.4.21-4.ELsmp on a Dell 1750 with 2 Emulex
LP9002DC-E HBAs. I've configured a RAID1 device called /dev/md10 from 2 SAN
based LUNs /dev/sdc and /dev/sde. Everything works fine until I disable one of
the HBA paths to the disk. Here's the console output:
[root@reacher root]# !lpfc1:1306:LKe:Link Down Event received Data: x2 x2 x0 x20
I/O error: dev 08:40, sector 69792
raid1: Disk failure on sde, disabling device.
