We use redhat linux ia64 , with emc . Since powerpath has no version on
our platform ( redhat 2.1) , we use 2 hba without any multipathing

You have to install any multipathing software in your system.If u r 
using Qlogic HBA they will be providing the driver with multipathing

like Veritas Volume manager.
