hello
we are planing to setup oracle RAC 10g R2 on AIX 5.3 using NAS storage
i will explain the steps that we will be using
please comments these steps:
we have 2 nodes "A" and "B"

1-on each node creation of groups "oinstall" and "dba" and user "oracle" all with
the same ids
2-on each nodes creation of the following mount points:
local : "/u01/app/oracle/crs" for oracle clusterware binairies
local : "/u01/app/oracle/asm" for oracle asm binairies
local : "/u01/app/oracle/db" for oracle database server binairies
question : shall we have oracle clusterware or asm on different mount point like
"/u02/crs" or "/u02/asm" and why ?

also created the following shared mount points each on a separate disk
shared : "/s01/cr1", " /s02/cr2" for the cluster registry also
shared : "/s03/vd1" ,"/s03/vd2","/s03/vd3" for the voting disks also
shared : "/A01/data1","/A02/data2","/A03/data","/A04/rec1",
for the asm datafiles and recovery files respectively
these disk have the same PVID on both nodes

is it fine so far ?
last question: is load balancing and failover configures by default after we finish installation, or shall we configure ir after the installation
any feedback is highly appreciated
many thanks
