Let me try to understand what you’re trying to do:
2 HBA’s going through 2 fabrics to a CX700?.
I assume you have connected SPA0|SPB1 to FabricA and SPB0|SPA1 to FabricB and done the zoning
here are some checks
1) check if the server is registered with the array
2) is the server and the luns you want to see in a storage group? (assuming acceslogix is turned on)
3) do you have powerpath installed (Failovermode 1)
If the above is done, you should see 4 raw devices (paths) for each power path device. the powerpath devices should be called emcpowera, emcpoweerb, and so on
