recently we connected a CX-300 to HP-UX server.we are getting only two paths to the LUN.do we need to use power path to get all the 4paths to the LUN?

our connectivity is as follows-SPA0&SPB0 is connected to Switch0(SW0) ,SPA1&SB1 to SW1 , HBA1 to SW0 and HBA2 to SW1.we did the zoning properly.while doing the ioscan in HP it's showing only two paths.is it something to do with the powerpath?

any help

thanks,
