The other thing is that you created your datafiles at 32k- I am forgetting how 
orion works but if your OLTP is using a different block size (8k ? ) this might 
cause some anomaly:  The vast majority of my projects use 8k block sizes.  Just 
make sure to test orion using the same block size as your planned db to 
maintain results that are comparable.

Hi Jon

Thanks for your help on this...

Attempt 1 orion.lun was:

/orion_test/test1.txt

Attempt 2 orion.lun was:

/orion_test/test1.txt
/orion_test/test2.txt
/orion_test/test3.txt
/orion_test/test4.txt
/orion_test/test5.txt

Attempt 3 orion.lun was:

/orion_test/test1.txt
/orion_test/test2.txt
/orion_test/test3.txt
/orion_test/test4.txt
/orion_test/test5.txt
/orion_test/test6.txt
/orion_test/test7.txt
/orion_test/test8.txt
/orion_test/test9.txt
/orion_test/test10.txt

Attempt 4 was the same as 3 but with -num_disks 24 passed at the command line.

/orion_test was mounted with the Oracle/NetApp recommended mount options for 
RAC data files

I  just remembered reading this thread when doing my research recently:

//www.freelists.org/post/oracle-l/ORION-num-disks,12

It seems to chime with what I'm seeing, so could be another approach to try...
