[Linux-cluster] RedHat HA Cluster and Software RAID?

I'm setting up two servers in an HA cluster (no GFS, just an active
service system and a standby).
I have 2 external hardware RAID devices that have 2 SCSI channels each.
I have 2 SCSI HBA's in each host.
The external RAID devices only have a single RAID controller.
So for full single point of failure avoidance I would like to do
software RAID1 across the two external arrays.
The documentation I am reading says that software RAID cannot be done
on "shared" storage.
I am a little confused. I know the quorum drives may be "shared"
and a GFS filesystem might be shared, but is a filesystem used by an HA
Can I setup a RAID1 device that migrates to an active cluster member
with the service?
