As cluster wiki:


"Multipath devices are currently only supported for RHEL 5.0 and later with the use of device-mapper-multipath."

Additionally, I found in a HP document info about how to set up cluster. Acconding to that information it's supported with version 5.3:


It's not a Red Hat document but they are partners so....
