That will be the config once Veritas and/or EMC support HBA path failover on RedHat AS 3.0. Veritas will support it with DMP in version 4 due in Q2/04, EMC has not committed to a date yet with PowerPath. In the interim I'm trying to provide path failover using software RAID1 of two hardware RAID5 LUNs one on each path (two switches connected to two storage processors connected to two HBAs per server).

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?

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.
