Stack Same Path warning... recabling advice.

I am getting "Stack Same path" warning when running Config Advisor. This is because of the connectivity of the primary and redundant path on four stack of FC shelves  look like this:

 

1d, 1c

3d, 3c

11b, 11a

4d, 4c

 

I guess what this means, is if the module (example IOM on port 1 where 1d and 1c) breaks, then I lose the entire stack, am I right? potential loss of data? especially since we are using software base ownership (disk assign)

 

I plan to recable them, but I want to learn more, but I plan to recable them like these:

 

1d, 3c

3d, 11a

11b, 4c

4d, 1c

 

What will be the best approach on recabling them? Total shutdown? anything else need to be done on the OS level?

 

Thanks,

md
