Dear All,
We are using IBM p570 Servers with p6 processors and AIX 5.3 with TL7 along with HACMP 5.4 . Oracle 9i RAC database is installed in these servers. DS8100 is the storage for these purpose. For each lun, there are 8 hdisks are shown by the system and one vpath is coming. I want to know the concept of these mpio, vpath , sdd and sddpcm in detail. (How it was configured, whether load balancing is enabled in my system or not in IO Adapters , FC etc? )

Any help in this regard will be highly appreciated.

Regards
Sridhar
