Also you can chage the Failover mode from 1 to 4.  Failover Mode= 1.      Passive Not Ready; a command failure when I/O is sent to a non-owning SP.  Failover Mode= 4.      Asymmetric Active/Active.  Thanks 
i got a CX4-120 box , 4 fibre channel connection to SPA and SPB .  Server A  -connected to SPA and SPB  Server B -Connected to SPA and SPB  i'm running cluster and all my live lun running on SPA only. SPB lun is for backup purpose.  i wish to allow my SPB connection to gain access to SPA and load balance between them.  i got power path installed, but seems it doesnt work at all.
CX4 cross connect between SPA and SPB
