Normally, multipath support is provided by the adapter driver. For example, if you have qlogic adapter, then install the driver with multipath support.

Read, enjoy and pick your poison.

You need some sort of multi-pathing so you don't see each path multiple times. You can use the multi-path built into the HP QLogic driver or you can look at the Device Mapper Multipath Enablement Kit for HP StorageWorks Disk Arrays.
