Two options,
1. 1st install MPIO on this system (if you have on VIO, it won't help as you have a direct connection to SAN from the LPAR itself). I am less confident this might help you resolve the problem.

2. Add a fabric, and do the zoning, and then map the LUN.

With the way it is seen now, there are high chances of data corruption.
Thanks for the reply. I already have MPIO drivers installed in the VIOS. I will try with option 2 and post results. But with option #2 , I need to configure zoning.. I am not familiar with zoning, is it easy ?
